Add missing extern

[Andreas Jaeger <aj at suse dot de>]

In our bugzilla we got a report that an extern is missing (for details:
https://bugzilla.novell.com/show_bug.cgi?id=233835).

This results on static linking with -Wl,-warn-common in lots of these
warnings:

/usr/lib64/gcc/x86_64-suse-linux/4.1.2/../../../../lib64/libc.a(strtod_l.o): warning: common of `_nl_category_name_idxs' overridden by definition
/usr/lib64/gcc/x86_64-suse-linux/4.1.2/../../../../lib64/libc.a(setlocale.o): warning: defined here
/usr/lib64/gcc/x86_64-suse-linux/4.1.2/../../../../lib64/libc.a(mbrtowc.o): warning: multiple common of `_nl_category_name_idxs'

Ok to commit?
