For that matter, 'make check' for day-to-day usage should be able to
skip the gnulib subdirectory - the results in gnulib/tests will only
change if you upgrade the gnulib submodule, glibc, or some other core
component, which is not what we change on a day-to-day basis when
hacking gnulib, but is also something an autobuilder should be running
always.  I'll see if I can hack something up to speed up 'make check'
for normal users on the gnulib front, which we can then extend into
skipping Peter's new test.

GNU coreutils calls its variable RUN_EXPENSIVE_TESTS, defaulting to no,
but set to yes in autobuilders.  Sounds like the best type of naming
(maybe VIR_TEST_EXPENSIVE, to keep it in the VIR_ namespace).  Anyone
else want to chime in with a bikeshed color?
