ffmpeg | branch: master | Hendrik Leppkes <h.leppkes at gmail.com> | Sun Aug  5 10:23:50 2012 +0200| [2db097ca76cee7c046e84b57e8ae19f60b716e56] | committer: Carl Eugen Hoyos

configure: fix lib.exe check

Running lib.exe without parameters will always result in an error,
and failing the check.
Using the -list paramter results in a success if lib.exe is present.
