New description:
There are two problems with the MPIR `configure` script for Clang:
1) It uses `__builtin_malloc()` which Clang doesn't have, which is an MPIR
upstream bug (up to and including MPIR 2.6.0). The spkg simply removes
this test.
2) The "long long reliability" test fails with a linker error. This looks
like a Clang bug.
The spkg changes the test slightly for Clang.
