>Description:
I discovered (when porting the test case to FreeBSD ^/stable/10) that tests/lib/libc/gen/t_vis.c wouldn't compile because it lacked a copy of strvis which supported strvis_locale. In order to compensate for this, I added appropriate #ifdefs for VIS_NOLOCALE around strvis_locale.

This seems to affect NetBSD 7.0.2 as well when testing the build there (it fails before my patch).
