The fact is that i think if static init works then try to use that to boot up the system and then debug the dynamic case.. you can run libc.so with a dynamic executable as argument then you can debug the loader if you have no debug tools on the target then i think you can add dprintf's to early loader code in src/ldso/dynlink.c which may help in figuring out what fails > executables compiled with the cross-toolchain works on our desktops > but they don't on QEmu, and we've added all the dynamic libraries that > readelf request (only libc.so, libstdc++.so & libgcc_s.so).
