I am able to reproduce the build fail as well:
.config: -> Notice that all v8 arch other than K3 is disabled, expert
mode is enabled and few ancillary "optimization" of config
	  https://pastebin.ubuntu.com/p/w5t9Wvp2jJ/
Here is what I did:
 git checkout next-20190115
 wget -O inta.mbox https://lore.kernel.org/patchwork/series/377815/mbox/
 git am inta.mbox
 I put the above .config as my .config
 make oldconfig
 make drivers/irqchip/irq-ti-sci-inta.o

I got the exact failure as well..

I agree with peter than this should be fixed. randconfig would have
caught this anyways.. I did'nt bother looking further in the config to
figure out why the side effect, but glad it got caught early enough.

Thanks Peter.

Lokesh, I know you are out this week, will appreciate if you could post
a v5 once you are back?
