Makefile: Get rid of invalid paths

When wildcards are used in toplevel Makefile.inc it ends up appending
all items including regular files into subdirs-y which then are treated
as directories in "evaluate_subdirs" with "Makefile.inc" appended to
them. Check for a valid path (existing Makefiles.inc) before attempting
to process it.
