mtklein 9834696ed8 Work around missing __mulodi4() on ARMv7 + Clang builds. 
__mulodi4() is roughly,

    int64_t __mulodi4(int64_t a, int64_t b, int* overflow) {
        int64_t result = a*b;
        *overflow = did_overflow(result);
        return result;
    }

It's used by Clang's __builtin_smulll_overflow(), which is basically the same
except it swaps the positions of the return value and the out parameter.

DNG SDK in turn uses __builtin_smulll_overflow().

When building ARMv7 binaries with Clang, __mulodi4() turns up as a missing symbol.
That's because it's defined in a separate compiler-rt library.  I have not been
able to link that.  Instead, I've provided our own trivial __builtin_smulll_overflow().

Before this patch both nanobench and DM failed dynamically linking __mulodi4().  After this patch nanobench runs for a while, eventually segfaulting.  DM immediately segfaults.
