Great, thanks.  I think it was just the former comment why -fPIC was
needed ("for linking into shared libraries")  which was confusing.
After all neither is tcc generating PIC code for shared libraries
nor do we support building shared libraries on ARM at all.

Anyway, I fixed it.

Now, I suppose that all tests are OK.

Except maybe "42_function_pointer" on ARM64 and possibly ARM?

The question for still failing tests then would be:

Did they work originally and were broken later (and if so by
which commit)  or did they never work on that platform.

Thanks,
