tools/mm: fix undefined reference to pthread_once
Commit 97d5f2e9ee12 ("tools api fs: More thread safety for global
filesystem variables") introduces pthread_once, so the libpthread
should be added at link time, or we'll meet the following compile
error when 'make -C tools/mm':
gcc -Wall -Wextra -I../lib/ -o page-types page-types.c ../lib/api/libapi.a
