I can replicate it on my Sparky Linux image.
But it's tempermental, I can't always replicate it.

I *think* it's a bug with GNU make - I cannot replicate it on any BSD 
platform but then reallocarray is also present so that particular issue 
would never be hit either.

When it happens, I was able to build simply by touching src/eloop.c.
This changes the datetime, which make does use, implying it's a make 
issue, or maybe an issue with my Makefile, but I don't understand what 
or how.

The eloop_bench isn't really a test, it just measures performance of the 
chosen polling mechanism. I wrote it to highlight an issue with the 
kqueue implementation on NetBSD compared to other BSDs. Linux of course 
uses epoll.
