On 3.3 and later, we support this under hppa64-hpux. This was
the only way that I could see to support running initializers and
finalizers in a manner that was compatible with both the HP and
GNU linkers. This is done with a horrible set of macros and crtstuff.c.
Probably, I should write a hppa64 specific version of crtstuff but
I wanted to be sure the basics were ok. I believe that things
run in the right order at the moment but the HP dynamic loader
runs the arrays of init and fini functions in reverse order to
ELF spec.
