When we switched to an interposing table (commit 8495e8b1e9) for
cancelation points we stopped having concrete implementations of
__<syscall> and instead use __sys_<syscall> and __thr_<syscall>.
These entries of the form:
__weak_reference(__sys_<syscall>, __<syscall>);
seem to be intended to preserve these symbols, but they have no effect
as __sys_<syscall> isn't defined in the translation units in question.
