I'm a bit confused - what is the issue that you want to "fix"?  The fix 
I suggested was to change the name of Stage1Only to more closely reflect 
what it actually does: disable the building of the stage 2 compiler 
*binary* but not the *package*, and install the stage 1 compiler.  If 
you additionally want to disable the stage 2 package, you can add 
stage=1 to your build.mk, though the only reason to do that would be to 
speed up the build in cases where you don't need stage 2.

What is it that actually goes wrong for you?

Cheers,
