Review Request: JDK-8009196 install doesn't define $(AR) as /usr/ccs/bin/ar, results in ar: Command not found

[David Katleman]

Modification to an earlier fix which broke internal Solaris builds, 
because ar could not be found.

Rather than the hatchet Erik's fix took to the problem, separating the 
CROSS_COMPILE_ARCH portion into it's own if, and the second portion into 
it's own Solaris only if since the ccs path is valid only on Solaris, 
and the original fix was to avoid this whole section for Windows.

For reference, the original fix
