Thanks for your fix, now the only remaining issue on RPi is:

Test: 42_function_pointer...

I'll try to investigate this one too...

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,
