Is it a base part of the NetBSD distribution?

Yes, execinfo has been part of NetBSD since version 7.0 as far as I can see, and 7.0 was released many moons (or years) ago. We've branched 11.0, and 9.0 is about to be de-supported when 11.0 is released in terms of support for third-party packages via pkgsrc. Trying to build rust for anything older than 9.0 is most probably not going to work (too old in-tree gcc, for starters) -- today doing so for 9.0 is even sometimes a struggle.

Confirmed part of NetBSD since 7.0 (2021).
