Without easy access to a PA-RISC machine, you can resort to
Qemu.  The Debian hppa port can be emulated using one of the
emulators provided in the package qemu-system-misc.  If you
combine it with the package qemu-user-static (and also have
Debian ports keyring at hand), then you can directly debootstrap
a chroot able to run PA-RISC binaries:

	$ uname -m
	x86_64

	$ sudo debootstrap \
		--arch=hppa \
		--keyring=/usr/share/keyrings/debian-ports-archive-keyring.gpg \
		--include=debian-ports-archive-keyring \
		sid sid-hppa-chroot http://ftp.ports.debian.org/debian-ports
	I: Target architecture can be executed
	[...]
	I: Base system installed successfully.

	$ sudo chroot sid-hppa-chroot uname -m
	parisc

> Otherwise, could you provide me the output of `cpp -dM /dev/null` and

Feel free to checkout cpp_hppa.h in attachment; I obtained it
with the aforementioned method.

In hope this helps,
Have a nice day,  :)
