As I noted in
<http://sourceware.org/ml/libc-alpha/2012-11/msg00461.html>, some clog
/ clog10 tests have underflows shown as unexpected, that actually are
not spurious because the imaginary parts of the results are in the
subnormal range for IBM long double. This patch marks the tests in
question with UNDERFLOW_EXCEPTION_LDOUBLE_IBM.
Tested that this eliminates the spurious errors on powerpc.

* math/libm-test.inc (clog_test): Use
UNDERFLOW_EXCEPTION_LDOUBLE_IBM on two tests.
(clog10_test): Likewise.
Thanks, this is fine,
Andreas
