config: add a 'auto' value for the number of parallel jobs

When CT_PARALLEL_JOBS is -1, set the number of parallel jobs to the
number of online CPUs + 1. Update documentation to match.

I find this useful when building in the cloud. You can use the same
.config file and have the build adapt to the number of processors
available. Limited testing shows that NCPUS+1 is faster than NCPUS+0
or NCPUS+2.

    18       The GCC test suite includes a collection of various toolchain tests for GCC -
    19       it utilizes the DejaGnu test framework.
    20 
    21       For some tests a network enabled target with ssh server is required.
    22 
    23       A helper Makefile is provided for running the tests - please see the included
    24       README for information on how to run the test suite.
