COOL!
I'm happy to test, but can you shortly describe the required steps how I can build & test it?

With "user-only target of hppa" I assume this means that I can run hppa binaries
on e.g. x86-64, similiar to what is described here: https://wiki.debian.org/QemuUserEmulation ?

Interesting.
I assume nobody did, because there are a few hppa/linux/glibc users anyway ? :-)

If you like I can give you access to a hppa-linux box...
