This is, I'm afraid.
Fixed in 1.42.

I beleive what I did to turn this error into a warning was to do
"paxctl +m <rustc bootstrap compiler>" (or was it the "cargo"
bootstrap binary which needed this treatment?  I forget...)

Alternatively, if you have the space to fetch all the bootstraps,
you could bump the bootstrap for NetBSD/i386 to 1.42, add

# To build 1.42 with 1.42, this is required:
CONFIGURE_ARGS+=        --set=rust.deny-warnings=false

to Makefile, do "make makesum", and proceed to build 1.42 with
the 1.42 bootstrap which should already be available.
