[libc-trusty] Workaround a codegen bug in Clang

Certain version of Clang may emit a reference to __multi3 when compiling
__builtin_mul_overflow(uint32_t, uint32_t, &uint64_t). compiler_rt for
32-bit ARM does not contain this function. Work around the problem by
casting one of the arguments to a 64-bit integer.
