-    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.

-    toolchain/gcc: .init and .fini need to pick one ISA
-    
-    The .init and .fini sections are built by concatenating code
-    fragments. Putting mips16 code in the middle of a mips32 code block
-    doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
-    
-    This is specific to 4.6-linaro but is probably portable to other gcc
-    flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
-    hack not suitable for pushing upstream, but there is no mips/t-linux
-    or mips/t-uclibc and I am not going to touch gcc/configure for two
-    lines.

-    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.

-    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.
