Yes, I know about that problem - we just upgraded our own machines and 
encountered this same problem.

I was going to add a fix to the next PTLsim release, but then I realized it 
wouldn't work for people still using older linker versions.

I've come up with a patch (attached) that should work correctly for all 
versions of binutils. When it makes usage.o, it sets "-O elf64-x86-64" when 
compiling a 64-bit PTLsim and "-O elf32-i386" for 32-bit PTLsim.

Probably I'll have to come up with a similar fix for injectcode-32bit.o, since 
that's actually 32-bit code, not data. You can try to figure it out on your 
own while I do some more testing with various versions of the linker.

(see the attached patch)
