Draft: Make aportgen gcc work again
Adjust the gcc aportgen code to not use tracedeps, so we can generate working gcc cross aports again. This is not the most elegant solution (better would be figuring out in detail why tracedeps fails here and fixing it somewhere upstream). But at least it allows generating working packages without manually working around the issue like it had to be done for pmaports!5722 (merged) for now.
See individual commits for details.
