Allow the libm-test-driver based tests to have their verbosity set based
on the LIMB_TESt_VERBOSE environment variable. This allows the entire
testsuite to be run with a non-default verbosity.

Please call it GLIBC_TEST_LIBM_VERBOSE.
We should really use a known conventional prefix e.g. GLIBC_TEST.
We don't currently, but lets move in that direction.
At worse I see WAIT_FOR_DEBUGGER, PID_OUTSIDE_CONTAINER, TIMEOUTFACTOR,
TEST_DIRECT and TEST_COREDUMPS, which could all get cleaned up.

Adjust as above.

What happens if this conversion fails?
Please see how we do this with TIMEOUTFACOR:
326 /* If set, read the test TIMEOUTFACTOR value from the environment.
327 This value is used to scale the default test timeout values. */
328 char *envstr_timeoutfactor = getenv ("TIMEOUTFACTOR");
329 if (envstr_timeoutfactor != NULL)
330 {
331 char *envstr_conv = envstr_timeoutfactor;
332 unsigned long int env_fact;
333
334 env_fact = strtoul (envstr_timeoutfactor, &envstr_conv, 0);
335 if (*envstr_conv == '\0' && envstr_conv != envstr_timeoutfactor)
336 timeoutfactor = MAX (env_fact, 1);
337 }

Thank you for the review. I've posted a v2[1] with the changes you've
suggested as well as handling the strtoul() call in the option parsing
as well.
Thanks,
Joe
