The build failed after 3 hours.  I've attached the full build log.  The
final bit was:

--8<---------------cut here---------------end--------------->8---

My understanding is that "term-signal: 8" means the process (rustc) was
terminated by signal 8 (SIGFPE on my system according to "kill -l").  Is
that right?

I looked in the failed build directory, but I couldn't find a core
dump.  When I manually ran the command...

/gnu/store/jxq[...]-mrustc-0.8.0/bin/mrustc src/tools/cargo/src/bin/cargo.rs [...]

...it actually succeeded.

Does this tell you anything useful?  I will keep the build directory
around for now, so please let me know if you'd like me to check anything
else.
