fix nl_langinfo with static linking (BZ #16915)
For static linking the locale code avoids linking code and data for unused categories. However for nl_langinfo we know only at runtime which categories are used, so direct reference to every nl_current_CATEGORY symbol should be done. This was broken by commit bc3e1c127392da88d0c8bf2ae728147982a3d1bc where nl_langinfo_l and nl_langinfo have been merged and some code has been lost in the process. In order to detect locales issues with static linking, compile a version of tst-langinfo with static linking. Note: this is Debian bug#747103 reported by Raphael <raphael.astier@eliot-sa.com>
