Grab a Go 1.4 binary from Dave Cheney's site, use that to build go 1.5.
wget http://dave.cheney.net/paste/go1.4.2.linux-arm~multiarch-armv6-1.tar.gz
tar xzvf go1.4.2.linux-arm~multiarch-armv6-1.tar.gz
mv go go1.4
git clone https://go.googlesource.com/go
cd go
git checkout go1.5
cd src
./all.bash
Some tests fail, but go runs.
