Subject: [PATCH 4/7] Fix transitive dependencies (of static libraries)

The dependencies of these libraries are not reliably picked up by their
corresponding find modules. This change allows adding the required
dependencies by setting certain variables, e.g. within the toolchain file.

This change also disables the upstream hack for OpenSSL's dependencies
as it is even more hacky to hardcode the library names and the casing
they use doesn't even work when building on GNU/Linux.
