Build of faust-generated code fails when using GUI

[robinrosenberger]

Building a Faust-project on Bela fails if render.cpp is created with faust2bela -gui
Output is:
bela-error.txt

Faust version is 2.33.1-1 on Arch, same result with latest master-dev eee155d
Bela is the latest github-commit (4d704a0) on image 0.3.8b

not entirely surprising, as upstream FAUST moves at a much faster pace than our support for it. Will look into it at some point. For now, it is best to use the last-known-working FAUST version tagged in the knowledge base
