GCC accepts either parisc or hppa, at least in config.gcc.  I tend
to think the parisc form should be deprecated since no other PA-RISC
targets use it.  The others all use hppa.

With respect to hppa variants, this is a hopeless mess and I don't
believe this can be fixed.  For example, libgmp treats hppa2.0w as
indicating a 64-bit runtime.  I'm sure you have hit this.

Nominally, the first part of the target string represents the
architecture of the kernel, and not the userspace architecture.
This is not sufficient to configure runtime applications when multiple
architectures are supported by one kernel.
