Why wouldn't they show up in dynamic relocs? There's no other point
for having them! They are a speed optimization for the dynamic linker,
so that it needn't assume R_SPARC_32 may be unaligned.

Too bad, as this binutils change is required for things to work
on Solaris, which otherwise gets SIGBUS on the unaligned write.
