Good catch! I think checking only for selects done by Kconfig symbols
that are not "n" might do the trick. Expect a v2 one of these days.
The current load of issues (for allyesconfig on all arches except um) is
pasted at the bottom of this message (with some comments added). Looking
at that load I think it might be preferable to first most of fix those
issues before adding this to kconfig.

drivers/remoteproc/Kconfig:10:warning: 'REMOTEPROC' selects unknown symbol 'VIRTUALIZATION'
REMOTEPROC should be ARM or OMAP specific?
lib/Kconfig.debug:1024:warning: 'DEBUG_ATOMIC_SLEEP' selects unknown symbol 'PREEMPT_COUNT'
Perhaps fixed by selecting PREEMPT_COUNT only for architectures that
support it.

I guess one or more cases of !PARISC might do the trick. But the
underlying problem is quite complicated. See commit 80ab8eae70e5 ("ALSA:
Enable CONFIG_ZONE_DMA for smaller PCI DMA masks"). Rather nice quote
from Andrew Morton about adding these selects (instead of fixing the
underlying problem):
But then we'll just forget about it :(
