Hmm, it is somewhat ugly :(
My secret plan is to get rid of -fwhopr option for 4.6 and make -flto default
to hopefully most sane setting - that IMO should be WHOPR doing parallel make
from Make's default with sane partitioning decisions (to reduce time and space
needed to stream out partitions).

So for this reason it would be really nice to have things as transparent
as possible.  I guess GNU Make is not nice enough to drop us some environment
variable or something? :(
