Subject: [PATCH] Use go build instead of go install

go install doesn't like to cross-compile things. (Try running build.sh with GOARCH set to something other than what it "should" be.)

With go build, it appears that cross-compilation is really, really straightforward. Simply install a compiler for your target platform and set `GOARCH` and `CC` accordingly.
