[Nix-dev] enableParallelbuilding for many packages

Well, I tried to build everything just once.  So when one package failed
to build with -jN, I didn’t try another time to see if it would
magically build; knowing that a build succeeds X % of the time wouldn’t
buy us much, IMO.  :-)

That doesn’t make much sense to me.  Either a package’s build system is
parallel-safe, or it’s not; when it is, just use $NIX_BUILD_CORES,
whatever its value is.

Thanks,
