1. Detect symver attribute support …

   On Microblaze, builds will fail when trying to add symver information
   because  __attribute__((symver ..)) is not supported even though
   __has_attribute(__symver__) returns true.
   
   Support for symver needs to be detected via a compile test since
   __has_attribute can report false positives [0].
   
   Add a configure compile check for __attribute__((symver ..)) to ensure
   it is supported and define a variable to advertise support.
