Description
I have already successfully built rust 1.44.0 on NetBSD/amd64 8.0.
Next I'm tackling NetBSD/i386 8.0, but that is not going as expected, the build
errors out after hours of apparent successful building with
Compiling miri v0.1.0 (/usr/pkgsrc/lang/rust/work/rustc-1.44.0-src/src/tools/miri)

I'm confused. Why would the amd64 build succeed and the i386 build fail when
building the same sources, with what appears to be a rust language issue??
I expected the build on NetBSD/i386 8.0 to succeed.
Instead, this happened: (see above).
The bootstrap compiler is rust 1.43.1.
