No, that will likely get you the empty set.
The most repeatable results are obtained by using the source tree under test
to bootstrap a native compiler on the host first. If you use one massive host
to run all of config-list.mk, that extra preparation generally doesn't make
all that much difference (unless you happen to have a host with # of cores
similar to # of test targets).
If you run these tests on a host that also occaisonally does native bootstrap
tests, you could extend that script to specify a --prefix and install
the compiler
if it's good.
