This patch brings over a few features 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.
* -Werror-maybe-reset
Has the effect of -Wno-error if GCC_NO_WERROR is
set and not '0', a no-operation otherwise. This is
to be able to use -Werror in "make" but prevent
GNU autoconf generated configure scripts from
freaking out.
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?
