HV: make: append dependency checking targets to a given variable 

The current implementation of the check_dep_* macros always append the
prerequisite checking target to BUILD_DEPS, but there are some cases when some
prerequisites are only necessary for some specific targets instead of general
builds.

This patch adds a second parameter to the check_dep_* macros specifying which
variable the generated target should be appended to.
