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:
https://mirrors.edge.kernel.org/pub/tools/crosstool/
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, Willy
