Passing options like this in the "source" parameter of ld_assemble
isn't the cleanest way.  Better would be to twiddle ASFLAGS (See
ld-frv/tls.exp for an example).  I'll OK your patch changed to use
ASFLAGS.

Best would be to add an "asflags" parameter to ld_assemble but I won't
ask for that since I probably wouldn't bother to do so myself..
Preapproved if you do care to go that route.
