Jason Merrill via Gcc-patches July 7, 2020, 7:15 p.m.
The code snippet for this test was returning 1 if power10
instructions executed correctly. It should return 0 if the
test passes.

Approved offline by Segher with slight change. Will
push after posting.


	* lib/target-supports.exp (check_power10_hw_available):
	Return 0 for passing test.
