  -----------
  Avoid using uint64_t -> float conversion in random.randrange

GCC's uint64_t to float conversion uses doubles, and pulls in a pile
of double code in soft float mode. Cast the value to a soffset_t, which
covers the whole potential range of values.

  Log Message:
  -----------
  Clean up compiler warning flag usage

Stop duplicating compiler warning flags in chips/samd21 and chips/qemu. Switch
to -Warray-bounds=2, add -Wcast-align.
