21; Various linker options have a -Z added so that they can get to specs
22; processing without interference.  Note that an option name with a
23; prefix that matches another option name, that also takes an
24; argument, being mapped to a -Z linker option, needs to be modified
25; so the prefix is different, otherwise a '*' after the shorter option
26; will match with the longer one.
