Some time in 2013 the build process for aicasm got broken for the
cross-build case (it builds with the wrong compiler and header files).
I fixed it late in 2013 with a series of botched attempts that fixed it
in some case and broke it for some other case.  Eventually it got fixed
for all cases except apparently the old-school kernel compile method of
running make from the sys/config dir.  Now it has been fixed on head by
just nuking aicasm and checking in some firmware binary blob instead.
I'm not sure whether it makes sense to mfc that binary-blob fix to
stable branches or not.

I've distilled the end result of my build mechanism changes down to a
patch against stable-8, I'll attach it to this mail.  It lets me build
amd64 and arm on this i386 machine, so I think it'll let you build i386
on an amd64 host.
