ktest: Add an example config that does cross compiling of several archs

Add the config that I use to test several archs. I downloaded several
cross compilers from:

 http://kernel.org/pub/tools/crosstool/files/bin/x86_64/

and this config is an example to crosscompile several archs to make sure
that your changes do not break archs that you are not working on.

+# Example config for cross compiling
+#
+# In this config, it is expected that the tool chains from:
+#
+#   http://kernel.org/pub/tools/crosstool/files/bin/x86_64/
+#
+# running on a x86_64 system have been downloaded and installed into:
+#
+#   /usr/local/
+#
+# such that the compiler binaries are something like:
+#
+#   /usr/local/gcc-4.5.2-nolibc/mips-linux/bin/mips-linux-gcc
+#
+# Some of the archs will use gcc-4.5.1 instead of gcc-4.5.2
+# this config uses variables to differentiate them.
+# 
+# Comments describe some of the options, but full descriptions of
+# options are described in the samples.conf file.
+
+# ${PWD} is defined by ktest.pl to be the directory that the user
+# was in when they executed ktest.pl. It may be better to hardcode the
+# path name here. THIS_DIR is the variable used through out the config file
+# in case you want to change it.
+
+THIS_DIR := ${PWD}

+# This is important. A variable is used only in the config file and if it is set
+# it stays that way for the rest of the config file until it is change again.
