Hi Alexander,
Sorry for the late reply. You're definitely better off discussing
this on ports@-- there has been some work done on cross-building
ports, but it's fairly early days yet; the only real cross that can be
done with much degree of success is i386 on amd64 currently.
Your patch doesn't look destructive, but it could be better integrated
with TARGET_ARCH setting.
Chris
