Thanks.  This does look like a useful improvement.

There seems to be a few oddities here, e.g. a FPTR64 relocation
presented to a 32-bit toolchain will create a FPTR32 dynamic relocation
for it, and similarly a FPTR32 relocation presented to a 64-bit
toolchain will create a FPTR64 dynamic relocation for it.  This is a bit
odd, but I suspect these won't occur in practice.  And this is an
improvement over what we had before, since at least we correctly get
FPTR32 with a 32-bit toolchain which we didn't get before.

Do you have access to ia64-hpux to double check any of this?  ia64-hpux
should presumably be considered the ILP32 reference, and GNU ld should
be behaving the same as the hp linker.  We shouldn't be creating our own
32-bit standard, at least not without an extremely good reason.
