+#### When cross compiling Erlang/OTP using `otp_build', copy this file and set
+#### the variables needed below. Then pass the path to the copy of this file as
+#### an argument to `otp_build' in the configure stage:
+####   `otp_build configure --xcomp-conf=<FILE>'
+#### --------------------------------------------------------------------------
+
+### Note that you cannot define arbitrary variables in a cross compilation
+### configuration file. Only the ones listed below will be guaranteed to be
+### visible throughout the whole execution of all `configure' scripts. Other
+### variables needs to be defined as arguments to `configure' or exported in
+### the environment.
+
+### ---- `otp_build' only variables -------------------------------------------
+
+### Variables in this section are only used, when configuring Erlang/OTP for
+### cross compilation using `$ERL_TOP/otp_build configure'.
+
+### NOTE! These variables currently have *no* effect if you configure using the
+### `configure' script directly.
+
+## erl_xcomp_build - Build system.
+##    This value will be passed as `--build=$erl_xcomp_build' argument to the
+##    `configure' script. It does not have to be a full CPU-VENDOR-OS triplet,
+##    but can be. The full CPU-VENDOR-OS triplet will be created by:
+##      `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_build'
+##    If `erl_xcomp_build=guess', the build system will be guessed using:
+##      `$ERL_TOP/erts/autoconf/config.guess'.
+erl_xcomp_build=guess
+
+## erl_xcomp_host - Cross host system.
+##    This value will be passed as `--host=$erl_xcomp_host' argument to the
+##    `configure' script. It does not have to be a full CPU-VENDOR-OS triplet,
+##    but can be. The full CPU-VENDOR-OS triplet will be created by:
+##      `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_host'
+erl_xcomp_host=avr32-atmel-linux-gnu
+
+## erl_xcomp_configure_flags - Extra configure flags.
+##    Extra flags to pass to the `configure' script.

+### ---- Cross compiler and other tools to use --------------------------------
+
+### If the cross compilation tools are prefixed by `<HOST>-' you probably do
+### not need to set these variables (where `<HOST>' is what has been passed as

+##    if the system root has not been set. The system root might be needed
+##    for other things too. If this is the case and the system root has not
+##    been set, `configure' will fail and request you to set it.
+##
+##    NOTE: For AVR32, this should be set to the build_avr32/staging_dir

+##    compilation environment. If not set, this value defaults to
+##    `$erl_xcomp_sysroot', i.e., only set this value if the include system
+##    root path is not the same as the system root path.

+### ---- Optional feature, or bug tests ---------------------------------------
+
+### These tests cannot (always) be done automatically when cross compiling. You
+### usually does not need to set these variables. Only set these if you really
+### know what you are doing.
+
+### Note that some of these values will override results of tests performed
+### by `configure', and some will not be used until `configure' is sure that
+### it cannot figure the result out.
+
+### The `configure' script will issue a warning when a default value is used.
+### When a variable has been set, no warning will be issued.
+
+## erl_xcomp_bigendian - yes|no
+##    If `yes', the target system must be big endian. If `no', little endian.
+##    This can often be automatically detected, but not always. If not
+##    automatically detected, `configure' will fail unless this variable is
+##    set. No default value is used, i.e., `configure' will try to figure
+##    this out automatically.

+## erl_xcomp_linux_clock_gettime_correction - yes|no (defaults to `yes' on

+##    If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on the target system must

+##    versions typically less than 2.6).

+
+## erl_xcomp_linux_usable_sigusrx - yes|no (defaults to `yes')
+##    If `yes', the `SIGUSR1' and `SIGUSR2' signals must be usable by the ERTS.
+##    Old LinuxThreads thread libraries (Linux kernel versions less than 2.2)
+##    used these signals and made them unusable by the ERTS.
+#erl_xcomp_linux_usable_sigusrx=

+## erl_xcomp_linux_usable_sigaltstack - yes|no (defaults to `yes' on Linux;

+##    `poll()'.
+#erl_xcomp_poll=
+
+## erl_xcomp_kqueue - yes|no (defaults to `no')
+##    If `yes', the target system must have a working `kqueue()' implementation
+##    that returns a file descriptor which can be used by `poll()' and/or
+##    `select()'. If `no' and the target system has not got `epoll()' or
+##    `/dev/poll', the kernel-poll feature will be disabled.
+#erl_xcomp_kqueue=
+
+## erl_xcomp_putenv_copy - yes|no (defaults to `no')
+##    If `yes', the target system must have a `putenv()' implementation that
+##    stores a copy of the key/value pair.
+#erl_xcomp_putenv_copy=
+
+## erl_xcomp_reliable_fpe - yes|no (defaults to `no')
+##    If `yes', the target system must have reliable floating point exceptions.

+## erl_xcomp_gethrvtime_procfs_ioctl - yes|no (defaults to `no')

+#erl_xcomp_gethrvtime_procfs_ioctl=

+## erl_xcomp_clock_gettime_cpu_time - yes|no (defaults to `no')

+erl_xcomp_clock_gettime_cpu_time=yes
+
+## erl_xcomp_after_morecore_hook - yes|no (defaults to `no')
+##    If `yes', the target system must have a working `__after_morecore_hook'
+##    that can be used for tracking used `malloc()' implementations core memory
+##    usage.
+#erl_xcomp_after_morecore_hook=
+
+## erl_xcomp_dlsym_brk_wrappers - yes|no (defaults to `no')
+##    If `yes', the target system must have a working `dlsym(RTLD_NEXT, <S>)'
+##    implementation that can be used on `brk' and `sbrk' symbols used by the
+##    `malloc()' implementation in use, and by this track the `malloc()'
