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.
* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
the default for -O2/-Os, because they trigger gcc bugs
and can delete code with security implications.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.
