Hi,

I occasionally want to compile things on a single CPU only, so I use an
explicit "-j1" argument to make.

GCC, when compiling with LTO, will generate its own -j argument if it does
not find a jobserver, and will default to the number of CPUs.

It would be nice to have a way to force using a jobserver even when
building with a single CPU.
