This is what I got from wiki (and no I'm not the expert with m68k, so
corrections are welcome):
https://en.wikipedia.org/wiki/Motorola_68000_series (8 x 32 bit data
registers)

And I cannot say why it is not able to generate the correct code...

The proposed flag (-fno-inline) seems to be the most pragmatic solution
(the code in question is in futex-interna.c and the flag only affects
this port).
