Is there anything unique to Solaris we could use to detect that we had found the
Solaris getopt?  For instance, lack of getopt_long_only() is used to detect some
non-GNU getopts and the presence of the global optreset variable is used to
detect the broken BSD getopt.

This would be simpler than actually trying a test execution of getopt() with an
optoin string starting with "+".  Such test runs break when cross-compiling.
