Er. How? The only thing this thread has come up with is a powerpc-only
-mrelocatable option which apparently gives the magic word to the
linker to have it emit dynamic relocations. We need similar options
for 11 other architectures before we can even think about starting to
utilize this in a generic manner.

An ELF shared library has the dynamic relocations we need. So if we
build u-boot as an .so file, it should work in theory on most
architectures.
