Ok, that's the what.

Now the why.

I expect something like:

"When not setting both CC and LD, and trying to do XYZ, we'd run into a
failure which looks like QRS. This failure only will occur in a
situation where we try to DEF while wanting to GHI.

For the regular case, building ARM on ARM (on any
non-cross-build-situation), this is effectively a NOOP, because NOP (haha)"

Or something else that explains, but not that a change is justified
because there should not be many people doing things.

You know all about this because you have researched it, I don't. Share
more information.
