[LTP] [PATCH] Makefile: Fix module dirs search

[Martin Doucha]

Module dirs search runs relative to current working directory instead
of the source directory. In an out-of-tree build, the search for makefiles
will come up empty and grep will try to read from standard input, blocking
indefinitely. Search for makefiles relative to the source directory to fix
the issue.
