So they all put libraries / headers in the same staging_dir? Doesn't
that give problems with packages detecting optional stuff at compile
time that might not be available for a specific variant (E.G. one
variant has expat, and another doesn't - Some configure script checks
for expat and finds it in staging_dir even though it isn't going to be
there at runtime).

The same with the packages offering different versions.

I think a more common setup would be to install the toolchain
somewhere common (/opt/<whatever>) and then have multiple boards using
the same toolchain/c library but potentially different set of
packages(-versions) and their own staging_dir.
