#1269: use XARGS configuration variable
--------------------+-------------------------------------------------------
 Reporter:  knarf   |       Owner:  knarf              
     Type:  defect  |      Status:  new                
 Priority:  minor   |   Milestone:  ET_2013_05         
Component:  Cactus  |     Version:  development version
 Keywords:          |  
--------------------+-------------------------------------------------------
 The attached patch let's Cactus use a define variable XARGS, much like
 others (e.g., TAR). This is necessary on systems where the default xargs
 program cannot be used (e.g., pandora.hpc.lsu.edu). The patch also let's
 the flesh use this variable, making it compile on these machines.
