[Buildroot] [git commit] linux: adjust BR2_LINUX_KERNEL_IMAGE_NAME help text

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ea044ee20c8b1a53cd75bc85e257674b8c106ee7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The help text of BR2_LINUX_KERNEL_IMAGE_NAME is somewhat incomplete,
in the sense that it assumes just a filename can be passed, while it
can be a relative path, such as 'compressed/vmlinux.bin.z'. So make it
clear that such paths are relative to arch/ARCH/boot/.

Also, drop the part about this being only useful for Xtensa as this is
not true: on MIPS it might be needed as well for some specific image
types.
