[Buildroot] [git commit] ruby: add support for gmp as an optional dependency

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=9a9d64bb496215a8dfbfe23960141ee7bf86c203
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Ruby can now use gmp optionally, so make sure that if the gmp package
for the target is enabled, it gets built before the ruby package, and
the appropriate configure options are passed to Ruby.
