This is really a QEMU question. I've been focused on making cross-compilers
and using those to create kernels and a minimal native build environment I
could use to natively compile packages with. (The way I designed the thing
you could substitute real hardware for the qemu step, assuming you had it.
Or another emulator like armulator for a specific platform.)
I don't believe QEMU emulates parisc yet, although it adds new platforms all
the time. (It just grew an alpha emulation last month.) It's under very
active development.
