Changes:
http://www.ogdf.net/doku.php/tech:versions#v_201505_baobab
- Remove dependencies on math/abacus and math/coinmp, as they are
now bundled into the OGDF source tarballs and compiled from there
(COIN remains optional)
- Point MASTER_SITES to the official OGDF website
- Utilise USES=compiler:features to detect C++11 support, and
add compiler flags -std=c++11 if so (required for build to complete
without errors)
- Remove custom do-install recipe, and instead use default
make install target
- Take maintainership
