Meanwhile I have investigated this more:

I have put ld-uClibc.so into /lib through ignorance. Now the loader starts to 
search in his "own" directory first, so /lib is implicitly prepended to the 
default library search path, which causes a glibc libgcc_s.so to be found 
first -> SEGV.

After talking it over with some local friends, I think a sensible way to go 
forward now is to implement some multi-arch scheme [1] which would place the 
loader into /lib/i486-linux-uclibc/ as well as putting all other 
i486-linux-uclibc compiled libs under appropriate subdirectories of their 
canonical locations as well as fixing ld-uClibc to search those locations.


This requires "some" adjustments to the build process though.
