[Buildroot] [PATCH] gcc/gcc-final: pass TARGET_CFLAGS flags to configure with --enable-cxx-flags

[Max Filippov <jcmvbkbc@gmail.com>]

Currently only TARGET_ABI flags are passed to the final compiler
configure script and only when building for Xtensa. Since libstdc++ is a
normal library it should be built with full TARGET_CFLAGS on all
targets.

Pass TARGET_CFLAGS flags to gcc-final configure script for all targets
in the --enable-cxx-flags parameter.
