perl: Avoid race continually rebuilding miniperl

When we run "make install" we notice miniperl rebuilding multiple times.
Usually this is harmless however sometimes race issues occur such as
miniperl not being executable.

The issue is that crosspatch is a phony target so it always rebuilds.
Adding this as a dependency of miniperl means miniperl always rebuilds
too.

Avoid this by injecting a direct dependency avoiding the phony target.
miniperl is then only rebuilt when its input changes as desired.

Patch submitted to upstream perl-cross.
