Jakub Jelinek e4ba7a600e re PR libgomp/43706 (scheduling two threads on one core leads to starvation) 
PR libgomp/43706
	* config/linux/affinity.c (gomp_init_affinity): Decrease
	gomp_available_cpus if affinity mask confines the process to fewer
	CPUs.
	* config/linux/proc.c (get_num_procs): If gomp_cpu_affinity is
	non-NULL, just return gomp_available_cpus.
