This reverts commit 90c6b2eb31106f0766ab2b8e90c97472e4ac3c78.

Unfortunately this change may cause an infinite loop when library
rebuild is triggered from a test directory. E.g.:

$ cd ltp
$ make clean
...
$ cd testcases/kernel/syscalls/abort
$ make
...
make -C "/foo/bar/ltp/lib" -f "/foo/bar/ltp/lib/Makefile" all
make -C "/foo/bar/ltp/lib" -f "/foo/bar/ltp/lib/Makefile" all
make -C "/foo/bar/ltp/lib" -f "/foo/bar/ltp/lib/Makefile" all
make -C "/foo/bar/ltp/lib" -f "/foo/bar/ltp/lib/Makefile" all
make -C "/foo/bar/ltp/lib" -f "/foo/bar/ltp/lib/Makefile" all
make -C "/foo/bar/ltp/lib" -f "/foo/bar/ltp/lib/Makefile" all
...

Looks like some kind of race, so let's revert the commit for now.
