With some of the recent cleanups, it might very well be doable, but it
hasn't been *done* yet.

The installer code still rather assumes it is executed on an x86 host --
or at least a littleendian host which supports unaligned memory
references.  There has been work toward cleaning that up, but it pretty
much requires someone motivated enough to do it for it to happen.
