[FFmpeg-devel] [PATCH] Fix pkg-config detection when using a cross-prefix

[Kyle Schwarz]

The attached patch resolves a pkg-config issue.

When a cross-prefix is used, FFmpeg searches for a cross-prefixed 
pkg-config, and fails to use pkg-config if none if found.

This patch allows a native system pkg-config to be used if a prefixed 
one is not found.

This patch is mainly helpful for a cross compile environment, such as 
MinGW-w64.

Best regards,
   Kyle Schwarz
