build: remove obsolete parallel build related options

Always use the main make jobserver, which has been the default for ages

-		  This passes the main make process jobserver fds to package builds,
-		  enabling full parallelization across different packages.
-
-		  Note that disabling this may overcommit CPU resources depending on the
-		  -j level of the main make process, the number of package submake jobs

-		  Example: If the main make is passed a -j4 and the submake -j
