When running make with parallelization, running both "clean" and "lib"
with a single make invocation can lead to each target building in
parallel. It's bad if lib is partially done building something, and then
clean deletes what was built. This can lead to errors later on in the
lib target.
$ make -j9 clean lib

To avoid this sort of trouble, always invoke clean by itself without
other targets throughout the library. Don't run clean in parallel with
other rules. The only place where clean was run in parallel with other
targets was in list-symbols.sh.
