I commented out the offending line in gdb_print_insn_sparc, and
recompiled.  Everything seems to work according to the way I want, so
set architecture does work.  A peek at the code seems to indicate that
as well.

I will, however, try the most recent snapshot.

Since the code has made a conscious effort to set info->mach, I wasn't
really sure if everything else would work.
