libtool: fix empty "-L" in compiler_lib_search_path

If the compiler places a space between "-L" and the path, the path will
be skipped and only an empty "-L" will appear in the final
compiler_lib_search_path. This will cause the first library in postdeps
following compiler_lib_search_path to be accidentally skipped.

* libtool.m4: Fixed string comparison by adding missing 'x's.
