LOG: [compiler-rt] Disable tests for unavailable builtins (#158664)

The builtins `__fixunstfdi` and `__multc3` may be removed by the
preprocessor depending on configuration flags. When this happens, the
corresponding tests fail at link time due to missing definitions.

Disable these tests when the builtins are not available.
