HP: Drive shared library linking with compiler front end 

Previously we linked C, Fortran, and ASM shared libraries compiled with
the HP compiler using a direct invocation of the linker (ld).  This
behavior was left historically from support for an ancient HP C compiler
that did not know how to create shared libraries.  Fortran shared
libraries need to be linked with the compiler to get the language
runtime library dependencies as is already done for C++.

Update the HP-UX-HP* platform information to use the compiler front end
when linking shared libraries.  This works on modern HP tools and
produces correct behavior.  If there is a need to support older tools
again we can add a special case for them.
