That line is here:

	input-files   := $(foreach hdr, $(header-y), \
			   $(or \
				$(wildcard $(srcdir)/$(hdr)), \
				$(wildcard $(oldsrcdir)/$(hdr)), \
--->				$(error Missing UAPI file $(srcdir)/$(hdr)) \
			   )) \
			 $(foreach hdr, $(genhdr-y), \
			   $(or \
				$(wildcard $(gendir)/$(hdr)), \
				$(error Missing generated UAPI file $(gendir)/$(hdr)) \
			   ))

The version of the compiler shouldn't have any effect as far as I can see.
Can you add the following:

	$(info XXXX $(srcdir)/$(hdr)) \
	$(info YYYY $(oldsrcdir)/$(hdr)) \

immediately before the marked line and look for the lines in the output from
make.  The error suggests that neither pattern match worked.

Btw, are you supplying an O= flag to make when you build?
