NAK.  If different images need to be linked with different text base
addresses, they should use separate variables.

Having these lists of #ifdef's and needing to know "umm, now we're in
the context of building FOO image, so TEXT_BASE might be that; oh,
wrong, it's the other #if branch actually, it should be this" is just
what you see right now: a maintenance nightmare.

Lets get rid of this mess, and use a separate variable for each
separate purpose.

Name space is big enough, so we don't have to redefine the meaning of
variables like that.

Best regards,

Wolfgang Denk
