(easier to find the relocation when you have the base of the library in
memory, really odd alignment, by the way)
All in all, it looks to me like it used to work by mere luck, but
somehow now fails because the lib containing the _restgpr_29_x symbol
is too far, which libgcc_s.so would likely be as well. So using a
R_PPC_REL24 relocation for these undefined symbols looks like a big
stretch.
