Subject: [PATCH] Flush stderr when not immediately exiting

When printing warnings on stderr that don't immediately exit pkg-config,
flush it so that the messages appear in order with stdout. This is
mostly to keep the test suite passing on Windows where output may appear
differently than on Linux.
