   4 Subject: [PATCH] bfin: remove inline keyword
   5
   6 Xenomai user space tools fail to build for bfin target since it's
   7 provide it's own pthread_atfork(), shm_open() and shm_unlink()
   8 definition using the inline keyword and weak attribute.
   9
  10 With gcc 5+ the weak attribute is discarded by the inline keyword,
  11 so each symbol are global and are redefined several time while
  12 linking.
  13
  14 Fixes:
