[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=2357f9f6698b7501dfb8c8b1eeb8a715a66a6929
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

Fixes: https://gitlab.com/buildroot.org/buildroot/-/jobs/1758965994

To correct a build breakage after the move to a gcc 10.x based host
compiler, as the updated kernel contains a fix for:

HOSTLD  scripts/dtc/dtc
/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here

Also correct a mistake in the kernel headers version comment.

Build-tested only.
