this is a RFC, I think it can also be used on qt 4.6.x and on armv7.
Setting QT_ARCH to armv6 enable some asm optimized functions in QT.

Do you know the consequences of this change? E.g. in the painting
engine unaligned memory access will be allowed.

1.) record a trace (e.g. the qtdemo) you will need Qt/X11 for that (desktop,
device). But make sure that the qtdemo width/height fits on the screen.
$ qttdemo -graphicssys
