Btw, there seems to be a bug in the sym-version code that crashes
tcc when it tries to link with a .so, for example:

    echo "void f() {}" | tcc - -shared -o a.so
    echo "main() {}" | tcc - a.so
    <segmentation fault>

I cannot reproduce this. I checkout a fresh copy and see no problem.
I use Fedora 31 with all updates.

see for example

 +./a.exe: error while loading shared libraries: ./a1.so: unsupported version
   25960 of Verneed record
I could reproduce this. The attached patch fixes this.
