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.

     1 Make psignal prototype in libiberty match that in glibc.

    15 when building on red hat 7.1
    16 though it's a bit of a mystery why libiberty's psignal is being compiled at
    17 all, since red hat 7.1's glibc supports psignal (hence the error message)
