C'mon, this is easy to solve. Just make sure that the build tool can be built 
with other tools, at least a minimal version to bootstrap itself. Qbs today 
has a qmake-based build. Qmake can be built with a simple Makefile, one that 
doesn't even require GNU Make. CMake has a bootstrap mode too.

The problem of the Qt dependency can be solved by copying the necessary files.

Why are we even discussing (1.b)? That's got a technical solution.

I thought that (2) and (3) would be a lot more contentious. Especially (2.c).
