libc/eglibc: fix localedef 2.14 build

The localedef of eglibc 2.14 requires NOT_IN_libc to be defined in order to
compile intl/l10nflist.c.

This is because localedef is built separately from eglibc and uses some parts of
eglibc that don't compile in standalone without this preprocessor definition.

This fixes the following error:

When fnmatch detects an invalid multibyte character it should fall back to

single byte matching, so that "*" has a chance to match such a string.

Andreas.

	* posix/fnmatch.c (fnmatch): If conversion to wide character

	fails fall back to single byte matching.
