Well, I sent a patch "[PATCH, RFC] Make arm926ejs use -march=armv5t to
avoid problems with EABI", which corrects this for me, although I'd
like some input on if it really makes any sense.

The main difference I see between the two binaries is the use of
ldrd/strd instructions, which comes with the "e"-version of armv5t.
Obviously, that shouldn't by itself produce broken binaries, so
something is still fishy here.
