First pass, I don't see a vendor directory that needs to be deleted, and
it does seem to only really depend on go-golang-org-x-sys, which is
nice. There is an npm directory which is where the compiled binaries are
placed, there are a couple in the checked out repo.

`esbuild --help` still works after removing the npm directory.

Is it worth trying to run some of the test suite? I see there are a
couple of 'make check' type targets in the Makefile at the root of the
repository and currently there are none run during the build.
