Yann E. MORIN 2c41fb6225 support/tests: allow top-level parallel builds
Running tests with top-level parallel builds can speed up running some
tests, expecially those that have a lot of packages like the systemd
init tests.

Trigger TLPB when the configuration enables per-package directories.

We're using the jlevel argument, which normally is used for BR2_JLEVEL
as the value for calling make -j<N> at the top-level. In fact,
BR2_JLEVEL is "unused" when using TLPB, because the top-level make
acts as the job server that distributes tokens to sub-makes (except
for the few build systems like waf or scons that don't support this),
so it's really the top-level make -j<N> that determines the level of
parallelism, and BR2_JLEVEL doesn't really have an effect.
