#
# Builds everything (std) for every GOOS/GOARCH combination but installs nothing.
#
# By default, runs the builds with -toolexec 'toolstash -cmp', to test that the
# toolchain is producing bit identical output to a previous known good toolchain.
#
# Options:
# -e: stop at first failure
# -nocmp: turn off toolstash -cmp; just check that ordinary builds succeed
# -work: pass -work to go command
