Mod to fix make depend for GASNet builds
Mod to fix make depend for GASNet builds

In my change yesterday to support the cray-xt-cray compiler
for GASNet, I inadvertantly broke the make depend step for
GASNet because the -I flags necessary to find gasnet.h got
dropped.  This mod fixes that issue by setting up a special
make depend line for chpl_cfg_comm.c.  It does not fix the
more general problem that we require GASNet to be built before
make depend will work properly (since gasnet.h will not yet
have been put in the install directory).
