The toolchain in the kit is mostly for use in C++ code model. The actual
build system is told what was set up -- if that is possible.

Which build system are you using?

Qmake is the odd one out here: It tends to hard-code compiler executable
names into its mkspec files and there is no reliable way to override it. So
this is kind of expected for qmake...

To have qmake pick up a non-default named compiler, you can try two things:
* Change the mkspec
* Create a folder somewhere, put a symlink called gcc/g++ into it and have
those links point to whatever gcc you want. Then set PATH to include your
folder before anything else that includes a gcc/g++ binary.

I hope this helps,
Tobias
