Hi Nick,

thanks for your suggestion. I was trying to make a test case when I found that
I used FSF overlay from older (2.20.1) binutils. With clean
binutils/gcc toolchain
kernel build passes. This brings up the following questions:
- is it still worth to debug the issue with the recent binutils +
older FSF overlay?
  (seems like the answer is "yes", because relaxation logic does not
belong to overlay)
- how comes that FSF overlay has different features in different
binutils releases?

Thanks.
