Controlix binary builds with GHDL support

I have gotten the GHDL runtime support and its associated dependencies to build, link and run. NuttX is crashing somewhere in pthread-land (probably because I'm not yet running any threads |->), but the grotesque amount of link-time bugs I was dealing with, mostly from libgnat, are finally dealt with. Now it is time to try linking in some of the old VHDL controls from the original SVN repository and see if I can get the GHDL runtime to work correctly....
