Unfortunately, I don't remember the details at this point; I ran into these
problems several years ago when I was finishing up the gcc dwarf2
implementation.

Perhaps the sparc64 Solaris binutils don't have this problem--perhaps the
sparc32 Solaris binutils don't have it anymore, either.  If the GDB
testsuite gets reasonable results when you use the system binutils, I would
go ahead with this change--but please do test with them, not just with the
GNU ones.
