This is where I insert my moan that the sysroot needs to have locking
and not modified during builds...

Maybe qemu-native should have a wrapper script that removes the
sysroot from LD_LIBRARY_PATH?  It's a native binary that doesn't need
anything in the sysroot, so let's stop it even looking there.
