 `main.o` for w/e reason has built for `x86`, despite the triple being
 correctly recognized in configure as `powerpc-apple-darwin`. I did not
 check the archive, and rebuiding now with `gcc10-bootstrap`, which is
 slow. Gonna check the contents of `libsample.a` after the build likely
 fails again.
