Subject: [PATCH] sys/types.h: Fixed the conflict issue with the "OK" constant
 definition

When cross-compiling PSE52 VSX testcases based on Vela, VSX defines its
own "OK" constant as a macro, which conflicts with the "OK" constant
defined as an enum in <sys/types.h>. To ensure compatibility, we
have undef'd the macro version of "OK" in advance.
