Static compilation of executable with tcc is sadly broken for a long time.

If you want missing symbol to be resolved from this library it should be last 
on the command line. Something like:

tcc -L/usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5/ -static main.c -
lgcc_eh.a

Honnestly I doubt you can compile glibc with tcc. It probably relies on a lot 
of GCC specific behavior and anyway, the support for inline assembly in tcc is 
not complete. I think we would all welcome any patch to improve this if you 
are motivated but trying to compile glibc will likely lead to an important 
quantity of fixes.
