[FFmpeg-cvslog] configure: improve the checks for gmtime_r and localtime_r

[James Almer]

ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Sat Jun  6 01:55:06 2015 -0300| [1b4dd59e5fbdebb8d9f13ad2dbdaa0179d0cce57] | committer: James Almer

configure: improve the checks for gmtime_r and localtime_r

They are inlined wrapper functions inside the time.h header on MinGW-w64, so
neither check_func() or check_func_headers() work with them.
