John Crispin be3937dfbc build: only track library dependencies of selected packages 
The prepare stamp of a Makefile depends on the library version files
of every package it defines, selected or not. Packages that are not
selected are not in the dependency graph of the top-level build, so
their libraries can be built after the package in a parallel build,
and the package is prepared and built again on the next run.

The own packages of a Makefile are only filtered out if they are
defined before the packages that depend on them. mac80211 defines
cfg80211 and mac80211 after the drivers, so it depends on its own
version files, and every clean build is followed by a rebuild of
mac80211, mt76 and linux-firmware.

Only add the library dependencies of selected packages, or of all
packages if DEVELOPER is set.
