Right. But I like to keep those crappy old preconfigured external
toolchains, because it forces us to test things with old gcc versions,
old kernel headers and all. Some users are probably forced to use old
gcc version for some reason, so I like to keep testing a bit the old
stuff.

You could object that we could continue to do this testing in the
autobuilders by supporting those toolchains as "custom external
toolchains" and not have them as preconfigured toolchains :-)
