This allows to specify paths for binaries in a new optbinaries=() array in PKGBUILD, which are not essential for the package and their dependencies can be considered optional. If a libdepend is needed only by optional binaries, then it's added to opdepends with a cumulated comment.
Add linked libraries to a packages dependency list. This is the partner
to automatically generated library provides, and thus depends take the
same format. To help with bootstrapping, library dependencies are only
added if the relevant provide exists.
