Its not a regression fix, so not really appropriate for the current stage of 
GCC 7 and the GCC 6 release branch, but is only a cosmetic change for all ARM 
variants except RTEMS. RTEMS releases are tied to a particular GCC version. We 
would like to use GCC 6.4 for the upcoming RTEMS 4.12 release.

If nobody objects I will commit this on Friday with corresponding release notes:
