pulseaudio: Workaround if clang 15

[franramirez688]

Summary

Changes to recipe: pulseaudio/[<=14.2]
Closes: #24464

Motivation

Configure step fails with:

checking for CFLocaleCopyCurrent... no
checking for GNU gettext in libc... yes
checking whether to use NLS... yes
checking where the gettext function comes from... libc
checking host operating system... linux
checking whether C compiler accepts -std=gnu11... no
configure: error: *** Compiler does not support -std=gnu11

Applying this workaround:

....

======== Input profiles ========
Profile host:
[settings]
arch=x86_64
build_type=Debug
compiler=clang
compiler.cppstd=gnu11
compiler.libcxx=libstdc++11
compiler.version=15
os=Linux
[conf]
tools.build:compiler_executables={'c': 'clang-15', 'cpp': 'clang++-15'}

....

checking if the linker (/usr/bin/ld) is GNU ld... yes
checking for shared library run path origin... done
checking for CFPreferencesCopyAppValue... no
checking for CFLocaleCopyCurrent... no
checking for GNU gettext in libc... yes
checking whether to use NLS... yes
checking where the gettext function comes from... libc
checking host operating system... linux
checking whether C compiler accepts -std=gnu11... (cached) yes

....

Details

Higher versions does not use Autotools and it does not fail

Great catch!

[franramirez688]

To clarify it a bit more. This workaround is bypassing this piece of code within the pulseaudio/configure script:

# ...

if ac_fn_c_try_compile "$LINENO"; then :
  ax_cv_check_cflags__pedantic__Werror__std_gnu11=yes
else
  ax_cv_check_cflags__pedantic__Werror__std_gnu11=no
fi
rm -f core conftest.err conftest.$ac_objext conftest.$ac_ext
  CFLAGS=$ax_check_save_flags
fi
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: $ax_cv_check_cflags__pedantic__Werror__std_gnu11" >&5
$as_echo "$ax_cv_check_cflags__pedantic__Werror__std_gnu11" >&6; }
if test "x$ax_cv_check_cflags__pedantic__Werror__std_gnu11" = x"yes"; then :
  :
else
  as_fn_error $? "*** Compiler does not support -std=gnu11" "$LINENO" 5
fi
# ...
