Comment(by jhpalmieri):
> I cannot explain why "make -j -lN" would fail but "make -jN" would work.
One reason is that `make -j -lN` puts a limit on starting new processes,
and that might be what's causing the problems. I could force the old zlib
spkg to fail on sage.math by running `MAKEFLAGS='j -l2' ./sage -f ...` but
not with `MAKEFLAGS='j -l30' ...`. I don't know if setting `MAKE="$MAKE
-j1 -l` in spkg-install is the right way to fix this for problematic spkgs
(like singular?), but it might be worth trying.
