[Buildroot] [PATCH] support/kconfig: fix linux header path

[Cherniaev Andrei]

Usually you will never have "/usr/src/linux"... For example on my Ubuntu 24 I have "/usr/src/linux-headers-6.8.0-47-generic". My change makes path universal.

Thanks for your patch. However, it cannot be applied as you did not
Signed-off-by on your patch.

Also, please wrap your commit message to 80 columns.

I actually don't think /usr/src/linux-headers-$(uname -r) is any
better. Most people who are interested in this will have their Linux
kernel source code cloned from Git, in some totally different location.
So perhaps:

"""
To update, assuming $KSRC points to a Linux kernel source tree:
	cp -a $KSRC/scripts/kconfig support/kconfig.new
	...
"""

Best regards,

Thomas
