[OE-core] [PATCH v2] postinst-intercepts, qemu.bbclass: fix segfaults in postinstalls

[Laurentiu Palcu]

Postinstalls that use qemu are throwing a segmentation fault when
building for qemux86-64 on a 64bit host (it might also happen for
qemux86 if building on a 32bit host but I didn't test). It looks like
qemu looks for ld.so.cache which is not found because it is generated
after rootfs_(rpm|ipk|deb)_do_rootfs is called and then it tries to load
libraries from the default paths (which are the host's). In order to
avoid this, pass the LD_LIBRARY_PATH explicitly to the target's dynamic
loader.

 * Addressed Richard's comment about multilib;

 Thanks,
 Laurentiu
