Why don't you just stop setting the damn strict alignment flag on ARMv6
and later instead this endless hacking around?

You really have only two sane choices here:

1. Keep strict alignment checking and build with -mno-unaligned-access.
2. Drop strict alignment checking and build with (implicit) -munaligned-access.

Option 2 gives faster, smaller code, so the choice should be an easy one
to make.
