Ah, right, the gnulib-generated Makefile.am files have to work also with
automake 1.10 and 1.9, so they can't blindly emit add `parallel-tests' to
the AUTOMAKE_OPTIONS.  Bummer.

Note that this objection is subtly wrong.  If gnulib could assume Automake 1.11,
it could simply add the `parallel-tests' option to AUTOMAKE_OPTIONS in the
gnulib-controlled Makefile.am.  This setting would only influence the execution
of the test cases provided by gnulib itself, and wouldn't have any impact on the
"global" testsuite framework used by the package.  It would be a win-win 
situation
for once.   But this is all moot, since gnulib can't assume Automake 1.11 (yet).
Oh well.
