As I told you in IRC, I thought that this was the case, because
freehdl-v2cc, compiles to C.

It turns out that there is a script (gvhdl), that invokes the C compiler
on the output files, so I have created a patch to wrap with the correct
environment variables, and also fix some issues on an extra script
(freehdl-gennodes) that is written in guile.

I reply with that patch, and also updated patches for qucs and qucs-s,
so that we do not propagate gcc-toolchain.

Thanks for your patience,
