gas 2.21 vs. arm-*elf target

[matthew green <mrg%eterna.com.au@localhost>]

it seems that there's a new bug in old arm-elf targets including
arm-netbsdelf.  i don't know what is going wrong yet, but something
in the new IT support is triggering a crash.

the simple hack below works around the crash by avoiding the code
that triggers the segv, and should be harmless for our current
system since we don't have IT support anyway (AFAIK.)

can someone have a look at what is really wrong please?
