xtensa: fix stack frame size for NPTL
Cancellable syscalls use call8 to call functions that enable/disable
cancellation, thus they cannot use the default FRAMESIZE.
Redefine FRAMESIZE for such syscalls.
This fixes the following testsuite failure:
.... tst-mqueue8
FAIL tst-mqueue8 got 1 expected 0
going to cancel mq_receive in-time
in-time mq_receive cancellation succeeded
going to cancel mq_receive early
Didn't expect signal from child: got `Segmentation fault'
