Configuration: support building for OpenVMS for x86_64

OpenVMS for x86_64 is currently out on a field test. Building programs for it is currently done with cross compilation on Itanium. The cross compilation tools are made available by running a script, which makes cross-compilation variants of most commands available, and adds the cross-compilation C compiler XCC.

+# The assumption is that *building* is done on Itanium, and then the source
+# tree and build tree are transferred to x86_64, where tests can be performed,
+# and installation can be done.
