[ncl-install] NCL for Power7

[Mary Haley]

This is a ppc64 system, correct?  If so, I think you want to be sure the
"StdDefines" line in your $NCARG/LINUX file does *not* have the
"-DByteSwapped" macro set.  Also, make sure you do *not* have this line in
the file:

#define ByteSwapped

I would look at the "LINUX.ppc64.xl" file for guidance on what the "LINUX"
file should look like. For example, the StdDefines line should probably
look like this:

#define StdDefines    -DSYSV -D_POSIX_SOURCE -D_XOPEN_SOURCE
-D_XOPEN_SOURCE_EXTENDED=1 -DNGLONG2XINT -Dppc64

I say "probably" because I don't know the details of the compiler you are
using. But, you definitely want "-DNGLONG2XINT -Dppc64" in the file.  The
"-Dppc64" is probably redundant, but shouldn't hurt.
