I found out what happened with this.

Uli never checked in the version that conditionalized the hpux check to
the binutils repository.  Ugh.

Instead of using a TARGET_IS_xxx, he has a macro which specifies an alternate
shared library extension to check.  That seems to make more sense to me as
other targets could potentially use it if necessary.
