Some time ago I looked into making u-boot PIC and I came to the conclusion
that one must be able to modify the GOT table before we have relocated to RAM.
Perhaps there is another way but didn't see it at the time, maybe there is some
"hidden" option to gcc that I missed.
The main problem are all those string literals, these are in the fixup table
and one wants to use printf and friends before relocation to RAM.
