With a CVS checkout from this morning, I don't see all of the failures
you list, but I do see some.  Here's my complete list of FAILs with
cross-binutils to all the targets you're trying.  (I'm pretty sure the
ld failures are unrelated, but I'm listing them just in case.)  In case
it matters, what host are you using?  I'm on x86_64-linux.

I will investigate all of the gas failures further.  On a cursory
inspection, none of them seems to have anything to do with Jan's macro
changes; they all appear to be either off-by-8 errors in relocs, or
places where tc-arm.c is expecting to be run on a 32-bit host.
