For go, generally yes, though you will have different binaries compared to a native build. In particular it links with libc differently; native build records a dependency on the libc version on the machine, go's crosscompiling just records it as "libc.so" (see objdump -p). There's no infrastructure for cross-compiling in the ports tree (and it's not particularly wanted in general) - you might be able to tweak individual ports to get usable binaries out of them with some languages and copy them out of the fake-install dir, but producing installable tgz packages will be trickier. -- Please keep replies on the mailing list.
