[svn-r10692] Purpose:

Cray X1 port

Description:
Added configuration files (config/nv1-cray) and made some minor changes
so that the 1.6 branch will build and pass tests on Cray X1 machines.

Solution:
hl/test/test_table will never compile if compiler optimizations are
turned on.  Optimization in test_table.c is thus disabled when __crayx1
is defined.

Platforms tested:
Cray X1s, eirene, sleipnir

+# after configure starts and defines, among other things, flags for
+# the various compile modes.

+# Compiler flags. The CPPFLAGS values should not include package debug
+# flags like `-DH5G_DEBUG' since these are added with the
+# `--enable-debug' switch of configure.

+# Choosing a C Compiler
+# ---------------------
+#
+# The user should be able to specify the compiler by setting the CC
+# environment variable to the name of the compiler and any switches it 
+# requires for proper operation.  If CC is unset then this script may
+# set it.  If CC is unset by time this script completes then configure 
+# will try `gcc' and `cc' in that order (perhaps some others too).
+#
+# Note: Code later in this file may depend on the value of $CC_BASENAME
+#       in order to distinguish between different compilers when
+#       deciding which compiler command-line switches to use.  This
+#       variable is set based on the incoming value of $CC and is only
+#       used within this file.

+# C Compiler and Preprocessor Flags
+# ---------------------------------
+#
+# Flags that end with `_CFLAGS' are always passed to the compiler.
+# Flags that end with `_CPPFLAGS' are passed to the compiler when
+# compiling but not when linking.
+#
+# DEBUG_CFLAGS         Flags to pass to the compiler to create a
+# DEBUG_CPPFLAGS       library suitable for use with debugging
+#                      tools. Usually this list will exclude
+#                      optimization switches (like `-O') and include
+#                      switches that turn on symbolic debugging
+#                      support (like `-g').
+#
+# PROD_CFLAGS          Flags to pass to the compiler to create a
+# PROFILE_CPPFLAGS     library suitable for performance testing (like 
+#                      `-pg').  This may or may not include debugging 
+#                      or production flags.
+#                      
+# CFLAGS               Flags can be added to this variable which
+#                      might already be partially initialized.  These 
+#                      flags will always be passed to the compiler
+#                      and should include switches to turn on full
+#                      warnings.  HDF5 attempts to be ANSI and Posix
+#                      compliant and employ good programming
+#                      practices resulting in few if any
+#                      warnings.
+#
+#                      Warning flags do not have to be added to CFLAGS
+#                      variable if the compiler is the GNU gcc
+#                      compiler or a descendent of gcc such as EGCS or PGCC.
+#
+#                      The CFLAGS should contains *something* or else 
+#                      configure will probably add `-g'.  For most
+#                      systems this isn't a problem but some systems
+#                      will disable optimizations in favor of the
+#                      `-g'.
+#                      
+#
+# These flags should be set according to the compiler being used.
+# There are two ways to check the compiler.  You can try using `-v' or 
+# `--version' to see if the compiler will print a version string.  You 
+# can use the value of $CC_BASENAME which is the base name of the
+# first word in $CC (note that the value of CC may have changed
+# above).
