When testing for ptheads support in the compiler, configure includes the CFLAGS value from the environment. If CFLAGS contains -pthread, or an option which implies -pthread (like -fopenmp), this will cause configure to not include -pthread in the CC variable, and -pthread will not be passed to the linker. This ultimately leads to a link failure when building with glibc/gcc. gcc -Xlinker -export-dynamic -o python Programs/python.o libpython3.7m.a -ldl -lutil -lm libpython3.7m.a(thread.o): In function `PyThread_start_new_thread': /home/floppym/src/cpython/Python/thread_pthread.h:191: undefined reference to `pthread_attr_setstacksize'
