I don't think that having _this_ test (32-bit with no sanitizer) fail when with non-AIX environments/configurations is acceptable. This is basically the same as the first test in the file (`CHECK-LD32`). If _this_ test is indeed failing, then please identify what the key difference is between this and the `CHECK-LD32` test.

Additionally, "on non-AIX targets" is not correct. Is it "on non-AIX hosts" or "with non-AIX target configurations"?
