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.

Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option is only
available to be selected by another config option. This option controls
if the Linux build system should build the DTB itself, or if buildroot
explicitly calls the Linux Makefile like "make something.dtb".
My use case: I want to build an OpenRISC image with a custom device tree
file. OpenRISC does not support appended DTBs, and I'm not using a
bootloader, but link everything into a single kernel (vmlinux) image.
The kernel option CONFIG_OPENRISC_BUILTIN_DTB allows me to specify a dtb
file, which is typically located in the kernel source tree in
arch/openrisc/boot/dts/NAME.dts.
Since my dts file is not part of the upstream kernel, I have two
options: either patch the kernel to include the DTS file, and then
specify it using the CONFIG_OPENRISC_BUILTIN_DTB option.
Or use buildroot's BR2_LINUX_KERNEL_CUSTOM_DTS_PATH config option to
copy any DTS file to the kernel source tree, and then specify this file
with CONFIG_OPENRISC_BUILTIN_DTB as before.
However, the second option also requries the buildroot option
BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT to be set, otherwise I end up with a
"make -C kerneldir NAME.dts" call, which doesn't work (no such target
exists).
Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option exists, but it's
not visible/available. Simply making it available solves the problem for
me nicely.

This issue only applies to kernels built with CONFIG_THUMB2=y, so reword the
comment to make that more clear.
Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
Commit f13477b (linux: config.in: add comment for Arm Cortex-M) added a
comment so that the user that the linux kernel may miscompile with
binutils 2.29+, when the target is an armv7m CPU.
However, the real trigger is a compilation in thumb2 mode, which happens
to be the only option for armv7m CPUs.
We can't know whether the kernel will be built in arm or thumb2 mode,
though, because we do not have that information: it is only available in
the Linux' .config file, which we don;t have access to at the time we
run our menuconfig.
So, relax the conditions under which the comment is made, so that it
appears as soon as binutils are >= 2.29 (i.e. not 2.28, which is the
oldest we support) for ARM CPUs.
