Good, but I think your change is wrong. The elf_machine_load_address() will
be called when you execute ldso directly(/lib/ld-uClibc.so.0). This is a
preparation for beeing able to do "/lib/ld-uClibc.so.0 /bin/ls". Just
try running /lib/ld-uClibc.so.0 with __SUPPORT_LD_DEBUG_EARLY__ enabled. You should
end up with:
"Cool, we managed to make a function call."
before is SEGVs.

I think you should add back _dl_boot in elf_machine_load_address() but you probably
need to define "extern void _dl_boot(void)" somewhere in dl-sysdep.h.
I tried to add a "extern void _dl_boot(void)" into ldso.c, but it turns out that
_dl_boot differs between archs.
