Nick Mathewson 6d6c8287d5 Include __mulodi4 in libor_ctime when it fixes clang -m32 -ftrapv
We use a pretty specific pair of autoconf tests here to make sure
that we only add this code when:
   a) a 64-bit signed multiply fails to link,
 AND
   b) the same 64-bit signed multiply DOES link correctly when
      __mulodi4 is defined.

Closes ticket 19079.

o Minor features (build):
- Detect and work around a libclang_rt problem that prevents clang from
finding __mulodi4() on some 32-bit platforms. This clang bug would keep
-ftrapv from linking on those systems. Closes ticket 19079.
