Subject: Enable qualified dependencies. Fix bug in internal 'build' command.

Added capability for CONTROL files to specify qualified dependencies, which are substring searched inside triplet names.

Fixed bug in internal 'build' command where if a package is already built, that built package's dependencies will be used to determine requirements for the build instead of the port directory's CONTROL file.
