./i686-native-linuxapp-gcc/include/rte_memcpy.h:592:23: error:
cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
dstofss = 16 - (int)((long long)(void *)dst & 0x0F) + 16;
Type 'long long' is 64-bit in i686 platform while 'void *'
is 32-bit.

v3 --> v2:
make dstofss and srcofs to be type size_t
casting type use uintptr_t
v2 --> v1:
Remove unnecessary casting (void *)
