Adding option 'usehighleveltool'

Adding option 'usehighleveltool', which gives preference to the higher level tool selection.
Default is false.

Currently 'usehighleveltool' is implemented for LinkType
operation to build a static library, i.e. 'outtype' target is 'static'.

If set to false (default), the default low level 'ar' librarian tool is being used.

If set to true, the high-level tool gcc, g++ or clang (w/ or w/o xcode's xcrun)
will be used to process the command.
This might have some advantages where xcode's clang may validate consistency
of the result, i.e. missing symbols etc.
