Use -fno-builtin for math tests...

[Andreas Jaeger <aj at suse dot de>]

As Gwenole pointed out, we do not use -fno-builtin for the math tests.

Now the ceil test fails:
testing long double (without inline functions)
Failure: Test: ceil (0.25) == 1.0
Result:
 is:          0.00000000000000000000e+00   0x0.00000000000000000000p-3
 should be:   1.00000000000000000000e+00   0x8.00000000000000000000p-3
 difference:  nan   nan
 ulp       :  nan
 max.ulp   :  0.0000

Test suite completed:
  2525 test cases plus 2312 tests for exception flags executed.
  1 errors occurred.

Ok to commit?
