We need to have one in the first place ^^ - if GDC could compile 
LDC, we could solve the issue that way.
Right now, we upload a new version of LDC, let it fail build or 
not-build, then Markos logs into a porterbox, bootstraps the 
current LDC there, rebuilds it with itself and uploads the 
resulting binaries to the archive. So, LDC can depend on itself 
then.

This works, until one LDC release fails to compile the other 
properly, then the bootstrap process starts again.

Btw, we have a request for an arm64 LDC package, but so far 
bootstrapping on that platform was unsuccessful.
