libc-config: avoid Clang’s __diagnose_if__
* lib/cdefs.h (__warndecl, __warnattr, __errordecl):
For now, do not use __diagnose_if__ here, as this fails
on Fedora 31 with Clang 9.0.1, with diagnostic
"/usr/include/bits/stdio2.h:263:9: error: fgets called with bigger
size than length of destination buffer
[-Werror,-Wuser-defined-warnings]". I guess Clang 9 warns even
for functions that are not called?
