svn commit: r202703 - stable/7/contrib/gcc/config/i386

Log:
  MFC 198344:
  Change gcc to assume a default machine architecture of 486 instead of 386
  on "i386".  Doing it in the compiler is deemed to be less fragile then
  attempting to provide a default -march setting via bsd.cpu.mk.  FreeBSD
  itself has not supported plain 386 CPUs since 5.x.
