Well you could but what I need to is satisfy the situation that if you
have --qemu-cc specified that it not use it. I'm not sure how you do
this in one line in bash. So I have
if [[ -z $cross_prefix ]]; then
qemu_opts+=" --cc=$cc"
else
qemu_opts+=" --cross-prefix=$cross_prefix"
fi
Also after this options are added to $qemu_opts based on what
architecture you are compiling for. For now you only see x86-64 & i386.
But this is about to change .. if I can ever get this patch in :-)
Also it becomes even more complicated with the next version of the patch
I'll be sending out in out.
