[ET Trac] [Einstein Toolkit] #1269: use XARGS configuration variable

#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.
