For R_x86_64_32 and R_x86_64_32S the problem is that the instructions are using absolute 32bit addresses. It is probably overkill but we should be able to solve this with by adding "-mcmodel=large" to the build of purgatory. Hopefully there are not 32bit or 16bit assembly routines getting linked in and using problemenatic instructions.
