I'm building an image for test, based on fsl-image-gui out of meta-fsl-arm.

It looks like that fsl image pulls in qt4 -

https://github.com/Freescale/meta-fsl-demos/blob/master/recipes-fsl/images/fsl-image-gui.bb

I don't quite understand why qt4 is rebuilding but if I had to guess
perhaps it's got a dependency on framebuffer support or something.

I could probably go in and change the image recipes if I really had to,
but I'd rather leave them as is, assuming correctness of dependencies,
I'd rather change an environment variable during my debug cycle to
temporarily contrain rebuilding of packages that I know don't need to
be rebuilt, so things revert to "correct" when I'm finished porting the
kernel

Cheers,

Alex
