New Revision: 302403
URL: https://svnweb.freebsd.org/changeset/base/302403

Log:
  Do not use -fformat-extensions with non-base versions of gcc
  
  Ports versions of gcc do not have -fformat-extensions support.
  
  This unbreaks compiling the kernel/modules with non-base gcc (4.8,
  5.0, etc) if MK_FORMAT_EXTENSIONS=yes (the default).
