Thanks, applied in r29128 with minor changes (typo, added some quotation
marks).

Yep, something like this, though I would do that before setting all variables
that use the ouput directory location. I haven't had a closer look yet, but
it might make sense to include some rules and do some build profile
processing earlier, so they are already available in the EarlyUserBuildConfig.

I wouldn't do that. I would leave EarlyUserBuildConfig completely optional.
Most people won't use it anyway, I guess. If one want to, one can just create
it.
