svn commit: r227679 - stable/8/sys/conf

[Doug Barton]

Author: dougb
Date: Fri Nov 18 21:04:59 2011
New Revision: 227679
URL: http://svn.freebsd.org/changeset/base/227679

Log:
  MFC r213077:
  Simplify how we find the kernel source.
  
  MFC r222218:
  expr -> sh arithmetic expansion
  
  MFC r226863:
  Fix svnversion for svn 1.7.x by not looking for .svn in ${SYSDIR}
  (since it no longer exists). Instead, run svnversion if we can find
  the binary and test that the output looks like a version string.
