Roughly speaking:

Start with the runtime specification for that architecture. In  
particular,
look at the relocations designed for shared linking. Those  
relocations need
to be supported by both the toolchain (gcc, as and ld) and the runtime
linker (rtld). Assuming that the toolchain already supports shared  
linking,
most of the work will be in rtld-elf.

After the basics work, look at TLS (more relocations) and gdb. You  
may need
to review threading support...

HTH,
