What I have seen in some cases is that the flags are used during
compilation too. In this case, using -lpthread issues a warning,
while using -pthread does not.

GCC, gcc: -lpthread: linker input file unused because linking not done
Clang, cc: warning: -lpthread: 'linker' input unused

It's more for consistency than correctness.

Admittedly, I'm not everytime patching s|-lpthread|-pthread| on my
PTHREAD_CFLAGS / PTHREAD_LIBS removal campaign.
