When the argument is rounded to float (0X1.118C64P+0), the correctly rounded
result becomes 0X1.D7C3B0P-6, so the error is 1ulp not 12ulp, and since there's
already a test of log10f in the testsuite with a 2ulp error recorded in
libm-test-ulps for x86_64, I don't think it's useful to add this test as well
or keep a bug open for this 1ulp error.

libm bugs remain suspended until somebody comes up with a patch.
