Pass the correct jobs and threads information to the builder.
We were underutilizing the number of jobs and threads specified
by the user.

number of threads. In that case make the number of threads
equal to the number of jobs and launch one jobs on each
thread. This makes things work like make -j.

--force-configure to force running configure before building.
--extra-llvm-config-flags
--extra-llvm-gcc-config-flags
--extra-gcc-config-flags
Pass additional argument to the various configure invocations.
