OpenJDK contains very outdated autoconf-config.guess and autoconf-config.sub
that don't handle triplet with -musl. It also contains wrapper scripts
config.guess and config.sub that we don't need at all.

This patch modifies these wrapper scripts to just include up-to-date
config.guess and config.sub from the icedtea tarball.
