Reuse number of jobs configured in MAKEFLAGS env var if available 

Especially on machines that are connected to a compile farm, the
MAKEFLAGS env var is usually set to configure the default number
of jobs that should be used. This way, one can just call the
PhantomJS build script without passing the number of jobs every
time.
