That's totally irrelevant.

Does S390 have ethernet or ethernet-like devices?  If so, the someday
it might in fact might want to use something like phylib instead of
adding yet another implementation of programming a particular PHY
chip.

So in fact, something like phylib should be possible to enable even on
s390.

And this current situation means s390 builds get less coverage, making
allmodconfig test builds (which the s390 folks are obviously doing
since they hit this originally reported build failure) less
useful than they could be.

I would even be happy to make it such that SBUS drivers can be
enabled for test building on x86, and in fact right now in
Linus's tree that's very close to doable.
