[Omake] Passing full target paths to compilers

[Jason Hickey]

I have added a --absname option that will force omake to use absolute 
pathnames for all files.

I am a bit dubious of this option, because it may have unintended 
side-effects (for example, when you create a symlink, with --absname it 
will link to the absolute name).

Also, omake considers rules to be out-of-date if the commands-text 
changes.  To minimize build times, you should avoid switching back and 
forth.

The --absname is a scoped option.  If you want to specify where it is 
used, use the OMakeFlags function.

    OMakeFlags(--absname)
    # --absname is now in effect

or even

    section
       OMakeFlags(--absname)
       ...
