I changed debug check in tccdbg.c on mob. Could you try again.

Was trying to compile X and noticed that it failed building hw/xfree86/ Turns out tcc was segfaulting by trying to deference a null address. Bisected mob to conclude that this regression was introduced by `ebaa5c8 dynamic executables (PIE)`. Also built tcc with its backtracing support and re-ran to get the following output: ``` 7f282ff1293c : by ??? tccelf.c:311: by section_ptr_add tccdbg.c:453: by put_stabs tccdbg.c:477: by put_stabn ``` And putting that all together, `section_ptr_add` received a null `Section` which implies `stab_section` is null. Double-checked this conclusion by adding an assert. Not too familiar with this part of the code so thought I'd just share my observations. Arthur
