Not sure about that: a full emulator like aranym can be used much like
the real hardware and can serve as a buildd, at least in principle,
without requiring system change.

The system-call-emulation is faster but the behaviour is special:
for example qemu will emulate exec("/usr/bin/gcc") by exec("/usr/bin/gcc")
on the native system and will run the native compiler not the emulated
one. I did not find an easy work around about that.
