The default ORC unwinder requires libelf to be built. While we could
build libelf using BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF, we probably
don't really need the ORC unwinder in the PC defconfigs, so let's use
the frame pointer unwinder instead.

Reusing the qemu x86-64 linux config isn't very obvious, so these defconfigs
aren't taken into consideration when the qemu defconfigs are updated,
breaking the build.
Instead use a custom linux config for the pc defconfigs. With this, we also
can get rid of the fragment file containing the delta fra the qemu config.
Created by linux-update-defconfig (after turning of the fragment file).
Also drop the linux kernel version number from the file name as it just
causes extra noise whenever the kernel is bumped.
