Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

I talked to Andrew about what files he changed in GCC and created and
tested this new patch. Andrew also mentioned changing some assembly
files in glibc but I don't see any use of '.section .note.GNU-stack' in
any assembly files in glibc (for any platform) so I wasn't planning on
creating a glibc to add them to mips glibc assembly language files.
OK to check in this patch?

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3
