binutils 2.34 has been released this weekend, it means that binutils 2.31 will
be removed after adding binutils 2.34:

https://lists.gnu.org/archive/html/info-gnu/2020-02/msg00000.html

So this issue will be trigged with all binutils version available in Buildroot
(2.31 -> 2.34).

Best regards,
Romain
