[This is based on the branch 'dev/wl/build-fixes'.]
The log file `snippet-names-c5b165525229969dd268a5b19f9f64fd.log`
contains
```
GNU LilyPond 2.25.14 (running Guile 3.0)

39638)
job 9 terminated with signal: 6

job 1 terminated with signal: 6
job 0 terminated with signal: 6
fatal error: Children (9 8 7 6 5 4 3 2 1 0) exited with errors.
```
AFAIK, signal 6 is 'SIGABRT'.
Note that the files `lilypond-multi-run-*.log` all contain
thread_suspend failed
which seems to be a hint that we have a problem with thread support on
macOS (Carl runs on macOS Sonoma which identifies itself as Darwin
23.2 on arm64e).
Any idea how to tackle this? BTW, `make doc` without `CPU_COUNT=10`
succeeds on his computer.
