Support for that kind of AS_NEEDED was added in 2005, back before Fabrice got 
too busy with QEMU to work on tcc.  In my repository, it's this commit:


I have personally tested my tcc fork on Ubuntu 7.04, which has a libc.so that 
looks exactly like that and is using gcc 2.5.  To confirm it, I just fired up 
qemu and built examples/ex5.c with tcc on that and it built fine.

Would you please once again confirm that you are using something more recent 
than 2005?  (Not just that you built it but that you actually installed it, 
and aren't getting an old one out of the $PATH?)  Because it's really, 
really, really looking like you're using an old version with bugs long-since
