I suspect that adding some more sections here makes the distance
between other sections too large to encode? IIRC, arm (32b) linker
can emit "range extending thunks" to help jump large distances. Not
sure what to make of this report; I wouldn't have expected this GCC
randconfig to generate code in any of the sections that were added to
the linkerscript in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=eff8728fe69880d3f7983bec3fb6cea4c306261f.
