"""
Build the Depends/Recommends for each of the API packages based on the
Build-Depends that are in the package. This is done to save repeating the
package names in multiple places.
Build-Depends used unconditionally are added to Depends
Build-Depends that are arch-specific are added to Recommends
The packages are listed in the debian/foo.substvars files so that they are
then picked when the binary packages are created.
