gcc on arm is actually validly complaining about us using int * ptrs
to point to char * data and thus it likely be unaligned, so work in
reverse. make the data int * aligned and when needed mess with it as
char * data byte by byte. warnings gone.
this fixes strict aliasing wanrings (-Wstrict-aliasing) whihc are a
result of imported md5 code being just really stupid with casting an
array to a ptr when there is no need.
