+
+    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.

+    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.
