Module Name:    src
Committed By:   mrg

Modified Files:
        src/external/gpl3/gcc/dist/libiberty: config.in configure configure.ac
        src/external/gpl3/gcc/usr.bin/backend: Makefile

Log Message:
use AC_USE_SYSTEM_EXTENSIONS in libiberty autoconf, which arranges for
_GNU_SOURCE to be defined for systems that need it (like glibc ones.)

be sure to find the right config.h for host programs.

these fixes combined make builds on debian 7 complete for me.
