The linux-2.6.18-xen.hg/scripts/Makefile.xen.awk script depends on the GNU AWK-specific function "gensub". If another awk is used (e.g., Debian installs mawk by default), the lack of gensub trickles down to cause the -xen.c files to not be compiled. This was time-consuming to track. So we should check that the awk program supports 'gensub'.
