[PATCH] [readline] Fix compilation on MinGW

["Christian Biesinger via gdb-patches" <gdb-patches@sourceware.org>]

S_ISLNK should not be called outside of an #ifdef.

However, this specific call is actually unnecessary, because
linkok can only be 0 if S_ISLNK is true, per the code above.

I have sent a bug report to bug-readline, though it does not show
up in the online archive yet.
