Nicolas Dufresne 7b0a5ad309 plugin: Explicitly link to BZ2, LZMA and LZ
While all this information is in the .la files, libtool seems to get
confused with ordering in presence of static system libraries. This could
cause missing symbol error at link time. Adding these depenencies explicitly
workaround the issue.
