getpwent is not available on android until API level 21, and even then it is only available when doing a non-static link. Since android's concept of users is very different from linux, it's doubtful the home directory resolution would be useful, so I approximate this state by just not using getpwent on android. We've had another getpwent occurance in FileSpec for a while -- it wasn't causing problems because it was stripped out by the linker, but I disable that also, for consistency's sake. llvm-svn: 297612
