New Revision: 229267
URL: http://svn.freebsd.org/changeset/base/229267

Log:
  Set ARM_ARCH_6 when CPUTYPE is set to armv6.
  
  Different set of atomic function should be compiled when armv6 is used, so
  when userland is built it has to know which architecture it will be used for.
  Now CPUTYPE=armv6 is used to tell that kernel and userland are built for
  armv6.
