portmaster with FLAVOR support available for testing

[Walter Schwarzenfeld]

Btw, I think it has nothing to do with FLAVOR, I found this (bug?)

sudo portmaster py27-setuptools

===>>> Working on:
     py27-setuptools-36.5.0
     py27-setuptools_scm-1.15.5

I only try to build py27-setuptools and portmaster wants to build 
py27-setuptools_scm too.

(The old portmaster version and the new)
