- 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

-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
