It depends on what's your FreeBSD and NetBSD versions are.  If both
are HEADs of CVS, I only had to add freebsd-7 and

+amd64-*-freebsd* | x86_64-*-freebsd*)

support into two files in the NetBSD distribution of gcc to make it
compile, but other than that it works (I use my 7-current amd64 box
dailyto cross-build NetBSD-current for a MIPS-based SoC).

I'm sure I reported it to the current@ list a while back.  I've
been able to reduce it to the length of 1, and for some time now,
I use my fastest box (amd64) to cross-build and cross-install
worlds and kernels for other architecture machines in my home
network (i386, alpha, and until recently sparc64).
