I suggest to wait until featureful GPL implementation of rust language
is made (assuming GNU Rust is on the way) before merging any rust code
in the kernel and when that implementation is done make a requirement
that all rust code must be buildable by at least GPL implementation.

Maybe it would also be worthwhile to make the requirement that the
kernel must be buildable with free software (not just open source
software) explicit ?

Or put the version of the compiler that works in the source tree
with the kernel and then build it as part of the full build.

That is an overkill :)
Even hosting a copy of all required tools at kernel.org might be an
overkill (but who knows);
I think having links at
https://www.kernel.org/doc/html/latest/process/changes.html#getting-updated-software
is enough.

It is enough of a PITA having to find libelf-devel in order to
build objtool, never mind having to find the correct version
of something else.

gcc tends to be available and the version doesn't matter too much.
But ever that gives problems.
