If you asked me, this has Dave Miller's name written all over it...  ;-)

The default shared objects on sparc boxes tend to be 32-bit objects,
so the "sparcv9" postfix is needed to explicitly select the 64-bit
shared objects.  None of that is needed for ia64.

It appears to be a gcc-3.2 feature: gcc-2.96 defines __LP64__ and
gcc-3.2 adds _LP64 on top of that.
