# set an environment variable for its location that we can use in .travis.yml for
# publishing back to github.

# linux 64 bit, not cross-compiled, breaks this rule and is in ${GOPATH}/bin
# therefore move it to match the convention of the others, to simplify subsequent steps
# note: we don't know what we built, so only move it if we happen to be linux amd64 travis job
