9.1-PRERELEASE is not too far ahead of 8.2-stable for building the system.
Advantage of a 64-bit OS over 32-bit OS for compiling is that 32-bit only
supports about 3 GB RAM, unless you use PAE, while 64-bit is not so limited,
but this is an issue only if you have >= 4 GB RAM.
FreeBSD is capable of cross-compiling the system for all supported
architectures ("make universe").
There have been questions on the FreeBSD lists on Clang vs. GCC for
building the system and ports.
