This removed patch is a workaround for gcc-4.5 manifests buffer
overflow with app-arch/tar-1.{22,23}, according to the information
from https://bugs.gentoo.org/show_bug.cgi?id=317139.
The problem with that patch is that it's only setting the magic
field of the header while the original statement sets both the magic
and the version field of the header. Because of this, all tar balls
created by the tar package in OE will be treated as old V7 format
tar balls.
As a negative effect of this behaviour, the tar package in OE cannot
handle device files correctly. This in turn leads to the udev cache
failure in images like core-image-lsb-sdk.
