Ok, I've verify this is working properly (not on MicroBlaze, but on other
architectures).
One observation, recent gcc appears to have changed something in CXX (at least
on x86-64), and I'm now getting:
../src/prelink: /home/root/prelink-cross/testsuite/cxx1: COPY relocations don't
point into .bss or .sbss section
when running the testsuite....
Anyway, what is there is now usable. I've got a small number of x32 patches
that need to be merged.. (that will come next.)
