The error suggests that neither pattern match worked.
Inserting
$(info XXXX $(srcdir)/$(hdr)), \ $(info YYYY $(oldsrcdir)/$(hdr)), \
did not work.

No. But supplying V=1 revealed that $(_dst) is an empty string at
# Recursion hdr-inst := -rR -f $(srctree)/scripts/Makefile.headersinst obj .PHONY: $(subdirs) $(subdirs): $(Q)$(MAKE) $(hdr-inst)=$(obj)/$@ dst=$(_dst)/$@
when using GNU Make 3.80, while $(_dst) contains appropriate string when using GNU Make 3.81.
With Make 3.81: make -f scripts/Makefile.build obj=scripts build_unifdef make -rR -f /usr/src/all/linux/scripts/Makefile.headersinst obj=include/uapi make -rR -f /usr/src/all/linux/scripts/Makefile.headersinst obj=include/uapi/asm-generic dst=include/uapi/asm-generic make -rR -f /usr/src/all/linux/scripts/Makefile.headersinst obj=include/uapi/drm dst=include/uapi/drm make -rR -f /usr/src/all/linux/scripts/Makefile.headersinst obj=include/uapi/linux dst=include/uapi/linux make -rR -f /usr/src/all/linux/scripts/Makefile.headersinst obj=include/uapi/linux/byteorder dst=include/uapi/linux/byteorder make -rR -f /usr/src/all/linux/scripts/Makefile.headersinst obj=include/uapi/linux/caif dst=include/uapi/linux/caif (...snipped...)
