Note that this looks more related to binutils here. Regardless, there
are pre-built toolchains including compiler+binutils for various gcc
versions from 4.9 and up here, for all supported architectures:

These ones are sufficient to build a kernel and are likely easier to
deal with than trying to port a patch over a bisect session. For example
you could have luck with 7.5 which has been supported for a very long
time and still is supported.

Hoping this helps,
