Linking to libmpeg2 is broken

[barracuda156]

When explicitly enabled, the build finds libmpeg2 normally, disables bundled lib, compiles vd_libmpeg2, but then does not pass -lmpeg2 to the linker. In result linking of mencoder fails due to a bunch of _mpeg2_* symbols.

Update. I just realized that you have some changes here as compared to svn upstream. I need to try building this specific version then. The linking failure occurs with the upstream branch.
