> Thanks! This seems to work for me for kernel-toolchain, then switching to a newer LLVM works around a RISC-V-specific failure in buildkernel, and it works! I'm still curious why the CI environment (and presumably others) don't need this patch; clearly there's some other divergence between the CI environment and my machine (and apparently Kyle's, too).

The way jobs get scheduled if you use -jN (N>1) seems to cause libztsd to
be built in time.  The Cirrus-CI job uses -j8.  I can reliably trigger
the bug on my mac with no -j argument or -j1, but with -j1.2 it builds
fine.
