[patch, gomp] PR29949 - implement argument checking for user accessable runtime routines

[Daniel Franke]

:ADDPATCH libgomp:

If the argument passed to omp_set_num_threads is negative or zero, set the
number of threads to 1.

Tested on i686-pc-linux-gnu.

	PR libgomp/29949
	* env.c (omp_set_num_threads): Set illegal thread count to 1.


If this is ok for trunk/4.2, could someone be so kind to commit it? (*)

Regards
	Daniel

done.
