The following errors are seen on PPC64LE while building Apple Swift 5 toolchain post changes pulled in commit d99579054bfe43ee3e92cf3e2c4a5357bdc7e0ef [NSNumber: Make comparing NaN with number match Darwin]

Can anyone please explain what these 2 tests are trying to test out? Since TestFoundation was working fine on PPC64LE before the above commit, is this a new feature added? If so, what is the purpose of this feature? I can see changes mention Darwin - "NSNumber: Make comparing NaN with number match Darwin". So is this test valid on PPC64LE?
