Message:

hostreqs: Bump Coreutils minimal version to 8.1 and check for nproc

We'll use nproc for setting MAKEFLAGS and TESTSUITEFLAGS. And if nproc
is not available, we'll end up with "MAKEFLAGS=-j" which is very
dangerous because it allows make to spawn infinite number of jobs.
Check it early.

The nproc program is added in Coreutils 8.1 so we need to bump the
minimal version.
