tpetazzoni flex: rework patches to avoid host/target difference
Currently, the target and host flex packages do not behave the same in
terms of patching: the target variant has a patch hook that disables
building the programs (because they are not needed, and do not build
on no-MMU platforms). However, this hook is obviously not executed for
host-flex, because we really want the host flex binary to be built.

In preparation for the introduction of out-of-tree package build, it
is important that we don't do different things in the patch hooks for
the target and host variant of a given package, because the source
tree will be shared between the target and host builds.

To solve this, we introduce a --disable-program configure option,
through a patch to the flex and This patch
makes the current 0001-flex-disable-documentation.patch no longer

Furthermore, building the documentation is a PITA: flex.1 depends on and a few other files generated during the build. Touching
flex.1 does not work, because automake will forcibly remove the files
when its prerequisites are too old, so pre-requisites of flex.1 will
always be more recent than flex.1. So, we add a patch that adds a
--disable-doc configure option.

  - rebase on-top of master,
  - add patch to not build the documentation, because simply touching
    flex.1 is no longer enough.
  - keep install in target/, for shared builds

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list:
You can also find us on #buildroot on Freenode IRC.
