--- Comment #1 from Florian Fainelli <florian at openwrt dot org> ---
strerror_r is marked with __must_check on glibc, and this leads to the
following warnings/errors (with Werror):

dwfl_error.c: In function 'dwfl_errmsg':
dwfl_error.c:158:18: error: ignoring return value of 'strerror_r', declared
with attribute warn_unused_result [-Werror=unused-result]
       strerror_r (error & 0xffff, s, sizeof(s));
                  ^
cc1: all warnings being treated as errors
