OK, Benjamin/Andreas/Dave, we could handle this case of failure using
the same technique I used (/copied from existing wrapper structure) to
handle generic implementation failures (I used a different report
string since the failure was different, i.e. the system may know about
the locale but the generic implementation couldn't handle it).

Under the assumption that missing locales shouldn't be reported as a
failure (in test case failure after test case failure).  Luckily, I
think we only have to modify the new and old wrappers.  I would
support one special test case that reported if a class of testing was
missing due to the lack of non-generic implementation and/or missing
locale used by the testsuite.  Could someone test it where these
locale names are missing (you may have a file failures after fixing
this but those are real failures to look closely at):

	* testsuite/testsuite_hooks.cc: Suppress runtime exception
	thrown when locale name is unknown on the local system.
