In exploring how other arches handle unifying 32 and 64 bit binutils, it
looks like they rely on a command line switch to get things set early
enough.  output_file_create calls TARGET_FORMAT before the asm file is
read, so we can't use the .LEVEL instruction to tell is if we're
elf32-hppa or elf64-hppa.

It looks like the best thing to do is to support the -march parameter,
similar to gcc.  gcc supports:

-march={1.0,1.1,2.0}

Should I add 2.0w to this for 64bit?  Talking about it with Randolph on
IRC, he pointed out that hppa2.0w-hp-hpux11.11 targets a 32 bit
userspace on a wide kernel.

HP/UX as supports the syntax:

+DAarchitecture

But I'd rather stick with something that feels more like the rest of the
arches and toolchain.

Thanks!
