Hopefully those *are* removable.

Unfortunately some packages depend on the 'qemu' meta package which
pulls in all of the emulators.

Libvirt will happily manage any subset of qemu-system-* that you have
installed.  It probes for what binaries are available when the
libvirtd daemon starts up.  However for some reason I can't quite
understand, libvirt-daemon depends on 'qemu'.  That may be a bug?

ppc is really three separate emulator binaries for different
ppc-related architectures (ppc, ppc64 and embedded ppc).  mips is also
three binaries (mips, mips64 and something called mips64el).
