unw_word_t is uint64_t even on 32-bit MIPS. Cast it to uintptr_t before the cast to void *p to get rid of the following errors:
util/unwind-libunwind.c: In function 'access_mem': util/unwind-libunwind.c:464:4: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] util/unwind-libunwind.c:475:2: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] cc1: all warnings being treated as errors make[3]: *** [util/unwind-libunwind.o] Error 1
