svn commit: r198344 - head/contrib/gcc/config/i386

New Revision: 198344
URL: http://svn.freebsd.org/changeset/base/198344

Log:
  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.
