I'm pretty sure this won't work.  mock would (via yum) try to install
RPMs which had %post scripts that would need to run PPC binaries.
Then the whole make/compiler would also be PPC binaries and so
wouldn't run in mock.

What I'm trying is to boot a Fedora PPC virtual machine, which I then
log into and run mock (or rpmbuild or whatever) inside.

PPC64 is a complete mystery to me though.  The errors I get from qemu
seem to indicate that 'qemu-system-ppc64 -cpu ppc64' doesn't
understand the 64 bit opcodes in the ppc64 kernel.  But it claims to
be emulating a PowerPC 970FX (which is a 64 bit processor, commonly
known as the G5).

Doesn't Fedora PPC64 have a 64 bit kernel and 32 bit userland?
