Module::Build does not have a feature. This is generally considered
unfortunate, but can not be changed anymore. A future replacement of
Module::Build might support it though. Though to be honest, MakeMaker
write out makefiles that are not particularly parallelizable, and even
if it did most build-times aren't long enough to benefit much from
them.

Actually, =C2=AB./Build test=C2=BB/=C2=ABmake test=C2=BB does support paral=
lelization
using the HARNESS_OPTIONS environmental variable, though this an
undocumented (AFAIK) implementation detail. I would rather like to add
a more comprehensive option for this TBH.
