Yes, this is what I meant above by "seed"ing the configurations, and it
is something I do all the time with my autobuilder here for things like
allnoconfig where I want to ensure that certain options have specific
values.

When I talked to Olof about it, he seemed to be against using the
facility in his autobuilder.  I'm not clear on why that was, but I
suspect it's because Olof wants to test real allnoconfig builds.

An alternative is we could have a HAVE_GCC_PR58854_FIX preprocessor
conditional, and pass in KCFLAGS=-DHAVE_GCC_PR58854_FIX to the kernel
to bypass the check.

Either way, I think we need Olof's input on this to say what he's
willing to do.
