>Description:
This patch adds -j (make jobs) support in do-build: with the user defined
knob of MAKE_JOBS (ie. MAKE_JOBS=4, would set -j4) , also ports can use 
MAX_JOBS (ie. MAX_JOBS=1, would set -j1 if MAX_JOBS < MAKE_JOBS) or NOMAKEJOBS and this would make MAKEJOBS empty.

This patch greatly improves compile time speeds esp. if used with distcc.
