Try using the tcc from Debian Squeeze then. It is based on version 0.9.25 (the 
last stable version) + a few patches from this development branch.

The patch to make string function work is maybe 10 lines and it's just about 
recognizing STT_GNU_IFUNC by replacing STT_GNU_FUNC by STT_GNU_FUNC | 
STT_GNU_IFUNC so you can take the stable branch, cherry-pick this patch 
(036d94112d4f0db6eb82b79bbfd0c9ef2328df34 if you don't know how to cherry-pick 
I'd be happy to tell you how to do it) and then recompile tcc.
