+ gcc/musl: rework SSP-support
+
+ Make musl provide libssp_nonshared.a and make GCC link it unconditionally
+ if musl is used. This should be a no-op if SSP is disabled and seems to be
+ the only reliable way of dealing with SSP over all packages due to the mess
+ that is linkerflags handling in packages.

+
+ gcc: prevent the use of LDRD/STRD on ARMv5TE
+
+ These instructions are for 64-bit load/store. On ARMv5TE, the CPU
+ requires addresses to be aligned to 64-bit. When misaligned, behavior is
+ undefined (effectively either loads the same word twice on LDRD, or
+ corrupts surrounding memory on STRD).
+
+ On ARMv6 and newer, unaligned access is safe.
+
+ Removing these instructions for ARMv5TE is necessary, because GCC
+ ignores alignment information in pointers and does unsafe optimizations
+ that have shown up as bugs in various places.

+
+ The .init and .fini sections are built by concatenating code

+
+ This is specific to 4.6-linaro but is probably portable to other gcc

+
+ 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.
- * -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.

+ gcc: don't clobber stamp-bits with a symlink to itself
+
+ Several versions of gcc have an issue in libstdc++v3 where the build may
+ clobber stamp-bits with a link to itself. This doesn't manifest itself
+ on all systems. On several Ubuntu systems, this doesn't appear to be a
+ problem, but it is an issue on Fedora 16 systems.
+
+ To fix the issue, we'll simply filter out stamp-bits from the symlinks
+ to be generated.
+
+ Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
+ there.
