Clean build without ccache didn't help.
It seams that it fails randomly based on the size of the rodata section.
This could probably happen with another toolchain too, trying enough
configurations.
Diff of tmp_vmlinux.kallsyms2.symbols and
tmp_vmlinux.kallsyms3.symbols [1] show why it fails to converge, while
said that the __stop_notes address is on the page boundary, so
__end_rodata has the same value as __stop_notes.
All 3 tmp_vmlinux.kallsyms(1|2|3).symbols files can be found [2].
Inserting padding before __end_rodata [3], or blacklisting __stop_notes [4]
in kallsyms.c works around the problem, but neither of those seems like a
good fix.
The linker version I'm using are 'GNU ld (GNU Binutils for Debian) 2.35.2'.
Cheers,
Anders
