Fix Bug 871 - Add optional xcode.clang support for all modules (Extends Bug 837 w/ xcode's xcrun)

Add 'isXCoderun' into the OO chain CommanLine[Compiler|Linker]
up-to [Gcc|Gpp]Linker and GccCCompiler.

Xcode's xcrun is now triggered via using the commands (linker and compiler):
  xcode.clang
  xcode.clang++

More could be added later ..

+++

[Gcc|Gpp]Linker are derived from GnuLinker
to reuse common code and to fix GppLinker (align to GccLinker).
