-    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.
