yes, they will fail but the errors won't trigger do_compile() to fail.
The loop in the top-level Makefile will continue to proceed.

headers_install is already called by some targets. The culprit is that
some of them missed to call it while they're using the generated
headers. Some other tests don't even bother and include uapi includes
directly. Because of this lack of consistency, I don't think it's
worth to try to use linux-libc-headers.

gpio Makefile is more brain damaged. I wrote a proper fix, submitted upstream:
https://www.spinics.net/lists/kernel/msg2473297.html

It needs to be slightly adjusted for 4.10, just lacked of time to send it here.
It can be in a v2 or a separate patch.
