Subject: make java components discovery follow symlinks

make java components discovery follow symlinks

When `--with-java` points to a symlink, `find` should resolve it, making
the configure script work seamlessly with symlinks pointing to JDK
installations.

This fixes the confusing discrepancy between `--with-java=/path/to/java`
failing and `--with-java=/path/to/java/` working.
