I agree regarding LIBS, but not regarding CPPFLAGS. If the program only
ever sees one thread, even though the library uses multiple threads behind
its back,
  - it does not need to #include <pthread.h>, and
  - it does not need to see a thread-aware errno,
hence it does not need to compile with THREADCPPFLAGS.
