Alternatively...

The "gcore" command is actually defined in gcore.c.  If someone
(hpux) wanted to define it differently, it should be as simple as
linking in your own (eg.) hpux-gcore.c module, *instead of* the
generic gcore.c module.

Current targets that implement gcore in the generic way
do so by adding gcore.o to the NATDEPFILES.
