Dependencies via libraries should be tracked via linking the libraries so
the ELF data records them correctly.

If the headers are required, the dependencies should appear on the
Requires.private: line, not the Requires: line - for most X software,
the Requires line should be nearly empty, and most things expressed
on Requires.private (which also handles static linking if needed).
