Makefile: Avoid continual rebuilds of miniperl and associated races 

In the Yocto Project, 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.
