Let me use an example to explain this one.

When machine/qemux86-64 fragment is enabled and users use 'MACHINE=xxx 
bitbake <pkg>', the expected behavior is to error out and recommend user 
to use 'bitbake-config-build disable-fragment'.

Here comes the problem. bitbake-config-build makes use of tinfoil and 
when setting up tinfoil, the above error will appear again. We can't 
recommend users to use 'bitbake-config-build disable-fragment' while the 
recommended method still errors out. This is the reason for the special 
exception.
