With upcoming BZ#12683 fix, syscall cancellation is not more handled
by {libc,pthread,librt}_{enable,disable}_asynccancel symbols. This renders
both LIBC_CANCEL_HANDLED and empty declaration and tst-cancel-wrappers.sh
unrequired. This patch removes both the macro and the nptl test.
Checked on x86_64-linux-gnu.
* io/creat.c (LIBC_CANCEL_HANDLED): Remove macro.
* io/ppoll.c (LIBC_CANCEL_HANDLED): Likewise.
* misc/pselect.c (LIBC_CANCEL_HANDLED): Likewise.
* nptl/pthreadP.h (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/generic/sysdep-cancel.h (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/mach/hurd/sysdep-cancel.h (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/posix/pause.c (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/posix/sigpause.c (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/unix/sysv/linux/creat.c (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/unix/sysv/linux/creat64.c (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/unix/sysv/linux/sigwait.c (LIBC_CANCEL_HANDLED): Likewise.
* sysdeps/unix/sysv/linux/sigwaitinfo.c (LIBC_CANCEL_HANDLED):
Likewise.
* nptl/Makefile [$(run-built-tests) = yes] (tests-special): Remove
tst-cancel-wrappers.sh.
(generated): Remove tst-cancel-wrappers.out.
(tst-cancel-wrappers.out): Remove rule.
* nptl/tst-cancel-wrappers.sh: Remove file.
