Commit Message

Florian Weimer June 14, 2023, 11:44 a.m. UTC 
These functions are about to be added to POSIX, under Austin Group
issue 986.

The fortified strlcat implementation does not raise SIGABRT if the
destination buffer does not contain a null terminator, it just
inheritis the non-failing regular strlcat behavior.

These changes missed updates to sysdeps/mach/hurd/x86_64/libc.abilist 
(presumably because that didn't exist when this patch series was first 
written), thus causing:

FAIL: glibcs-x86_64-gnu check
