Unfortunately not.

I've used the latest dizzy-Branch and applied this patch, but the behaviour did not change.

commit 219e793907406eabf632e784e3a11ab9acb77cfb
Author: Richard Purdie <richard.purdie@linuxfoundation.org>

    qemu/libc-package: Fix qemu option handling

    The 'overrides' here are PACKAGE_ARCH based and hence not overrides
    as such and the _append wasn't working in many cases. This adjusts the
    code to use PACKAGE_ARCH as the accessor and ensures the variables
    work as expected. This fixes various segfaults and ensures postinsts
    run at build time rather than on the target system.

    The bug was introduced in http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=7efad8a1b56df6ee07c12ad360c0493d7b1d6d23.
