Get Python LDFLAGS from 'pkg-config'.
The other approach is more complex and gets it wrong: it returns
"-L/path/to/python/lib/python-2.7.10/lib/python2.7/config -lpython -lwhatever";
since that config/ sub-directory contains libpython2.7.a, we end up
statically linking Python in Weechat's python.so, which we do not want.
