[FFmpeg-cvslog] configure: Add test_pkg_config()

[James Almer]

ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Fri Sep 29 22:56:08 2017 -0300| [d66fe7ff53a5cade7a702100a9006dfe5ae1c473] | committer: Diego Biurrun

configure: Add test_pkg_config()

This helper is split off check_pkg_config(), setting only the pkg CFLAGS
and extralibs. This is useful for checks that do not require or do not
benefit from setting global CFLAGS.
