We need to backport this commit to avoid a regression from glibc 2.28:

    string: strerror must not return NULL (bug 30555)
    
    For strerror, this fixes commit 28aff047818eb1726394296d27b ("string:
    Implement strerror in terms of strerror_l").  This commit avoids
    returning NULL for strerror_l as well, although POSIX allows this
    behavior for strerror_l.
