Any early out checks must give the same answer as FcConfigCompareValue.
An accelerator was added for family names which treated all ops as if
they were FcOpEqual, giving the wrong answer for other non-equivalent ops
(for example FcOpContains or FcOpNotEqual).
This adds a test which passes before the accelerator was introduced,
fails after, and will pass again after !142 lands. This tests the all
not_eq case.
The test-conf test requires libjson-c to be available in order to be
built. However, there has been no user indication that additional tests
could be built if the json-c development files were available.
Continue to not build test-conf if json-c is not available, but do run
the test harness. The test harness is updated to SKIP the test if the
test-conf binary is unavailable.
This causes a failure when evaluating $OSTYPE on systems which do not
set that variable (everything but Msys/MinGW)
