[MPlayer-dev-eng] [PATCH] External libass detection in mingw

[Josh]

External libass detection hasn't worked in MinGW; "-lass" isn't enough. 
Since libass requires freetype, -lfreetype is needed and -lenca is 
needed if compiled with ENCA. fontconfig is a non-issue, probably that 
it is checked before libass takes care of it.

This was the best I could come up with. The 'test "$ass_internal"' was 
factored out to its own "if/fi" otherwise internal libass didn't work if 
external wasn't present. Maybe a saner solution is needed but it seemed 
to work as intended at least under mingw.
