Right, its not that simple. As it happens I was just looking at this
patch:

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=rpurdie/t222&id=32afecae2495b0486a044b66154573caf39144c7

which I proposed a while ago which does solve this problem, with some
ugliness in base.bbclass. I know Ross doesn't like it, neither do I, I
do prefer it to the pretty horrible things PIXBUFCACHE_SYSROOT_DEPS does
though.

Cheers,

Richard
