Support parallelism for check-elf-dynamic-objects

using that and restricting the tests to the content of
instdir/program bring the runtime on out slave builder from
4 minutes+ to just above one second

added -d <path> to override INSTDIR
added -p to indicate parallelism (no limit for now, so be cautious
with the -d you point too
