Right. I was doing musl port

that nobody ever called or will ever call __sigsetjmp with call12 though.

window saving loop in __sigsetjmp incorrectly calculates offset
in the jmp_buf in case it was called with call12. The bug was introduced
in commit f4b1b7ade7971141 "xtensa: fix setjmp that didn't save all
registers correctly".
Thanks, applied and pushed.
How did you found it? No included testcase catched it, right?
