Temporarily workaround gcc warning
New gcc, new warnings:
../lib/str_error_r.c: In function ‘str_error_r’:
../lib/str_error_r.c:25:3: error: passing argument 1 to restrict-qualified parameter aliases with argument 5 [-Werror=restrict]
snprintf(buf, buflen, "INTERNAL ERROR: strerror_r(%d, %p, %zd)=%d", errnum, buf, buflen, err);
^~~~~~~~
cc1: all warnings being treated as errors
Bring in a quick fix for now.
