Thomas Weißschuh 3eb97c4cbd tools/nolibc: avoid -Wundef warning for __STDC_VERSION__ ...

With -std=c89 the macro __STDC_VERSION__ is not defined.
While undefined identifiers in '#if' directives are assumed to be '0',
with -Wundef a warning is emitted.

Avoid the warning by explicitly falling back to '0' if __STDC_VERSION__
is not provided by the preprocessor.
