Use -fno-builtin for math tests...

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?
