phantomjs-1.9.7 - two build breaks + two ugly fixes

[davidfavor (David Favor)]

Unsure how to best fix these. Leaving real fix to Port owner.

The following just shows one way to fix all the build breaks.

:::: Break #1: attempted use of local (missing) qmake instead of macports qmake

cd /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/www/phantomjs/work/phantomjs-1.9.7/src/qt/bin
ln -s /opt/local/bin/qmake

:::: Break #2: unrecognized -fconstant-cfstrings

g++: error: unrecognized command line option -fconstant-cfstrings

Locating all occurrences of -fconstant-cfstrings + removing them from all build scripts seems to work.

Both these fixes are very ugly. There must be a better way.
