[PATCH 3/3] Makefile.local: use $(wildcard) to check existence of ${srcdir}/.git

[Tomi Ollila]

With this GNU Make construct one shell invocation can be skipped
and code looks shorter (narrower). This would now match to .git
being other file type than regular file or directory (or symlink
to those), but that is not a use case anyone should expect users
to do.
