Simply, such usage currently is not part of the concept.  As it
is, tcc_relocate must be called only once for each TCCState.

I don't see right now why you would want that.

In principle it could be enabled, but there are some complications.
For example symbols need to be converted to SHN_ABS, old code needs
to be deleted, ...
