IIRC, you have clang 3.6, which means you shouldn't need the clang 3.5
patch at all (it was a bug in that version of the clang compiler only).

You should be able to build with "make ICOTOOL=true", you'll just end up
with an empty octave.ico file.

There was a recent change that figures for the manual are built by the
default toolkit, which means qt if available, then fltk if available,
then gnuplot. But there is no check ensuring that you also have osmesa
present and working. I could see that as a worthy enhancement, fall back
to gnuplot if no osmesa.
