Automatically run make on multiple cores
# Changes to defaults for "make"
# ============================================================
# How many cores do we have? Find out from /proc/cpuinfo (using regexp matching
# the start of info for a new processor).
NCORES=`grep --count '^processor[[:space:]]*:' /proc/cpuinfo`
# Apparently make runs fastest with one more job than there are cores.
NJOBS=$(($NCORES + 1))
export MAKEFLAGS="-j$NJOBS"
