commit: http://git.buildroot.net/buildroot/commit/?id=383287ce33c7e8780db3b2a3374aa0b2e57af889
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

If the libtool used by the package is 2.4 (i.e. with no patchlevel), we
end up with a confusing message:

    /bin/sh: line 0: test: -gt: unary operator expected

That's because patchlevel is empty, and thus there is nothing to comapre
to 2, and test complains.

Fake a patchlevel of 0 (which is really what a missing patchlevel means
anyway) in that case.
