Cleanly support debug packages

Browse Source 
Allow a source rpm to be rebuilt with debugging enabled.  This
avoids the need to have to manually modify the spec file.  By
default debugging is still largely disabled.  To enable specific
debugging features use the following options with rpmbuild.

  '--with debug'               - Enables ASSERTs
  '--with debug-log'           - Enables the internal debug log
  '--with debug-kmem'          - Enables basic memory accounting
  '--with debug-kmem-tracking' - Enables detailed memory tracking

  # For example:
  $ rpmbuild --rebuild --with debug spl-modules-0.6.0-rc6.src.rpm
