2020.02.x has GCC 9 and (should have) all relevant CVE fixes, so you can
build it yourself.

Correct. I am not quite sure what the logic is behind the version
choices done for the Bootlin toolchains, E.G. the kernel headers and
other components are quite old for the stable version, but glibc is the
same for both stable and bleeding edge.

I agree that it (currently at least) isn't a lot of patches, but it
becomes a bit of a slippery slope, so I would prefer to not add them to
2020.02.x.

What do others think?
