There are some issues with the following,
with sometimes tests being skipped and/or
sometimes output being misaligned.

(cd tests && make -j2 check TESTS="misc/stty misc/stdbuf misc/stat-birthtime 
misc/stty-row-col" VERBOSE=yes)

That's because gnu make in parallel mode, will give a single
one of its worker processes the controlling tty.
Also if misc/stty does actually run, the fact
that it messes with the current tty, breaks the
output alignment at least.

This isn't a major issue really.
and I'm not sure how to address it.

Perhaps we could split the "tty" tests,
to a separate Makefile containing .NOTPARALLEL ?

Perhaps we could make them actually support parallel mode,
by using expect or something?
