`strerror()` is not thread-safe, thus, we have to use an alternative. If we want to prevent allocating a temporary buffer (e.g., for `strerror_r`), we need to use `perror()`. To allow writing stored `errno` values, the function sets `errno` from an argument passed to it, which should be safe according to the manual. Signed-off-by: Felix Walter <felix.walter@d3tn.com>
