[Buildroot] [PATCHv2 1/4] package/ncurses: Allow building wide char support

From: Jeremy Kerr <jk at ozlabs.org>

Allow ncurses to be configured with wide char support; this causes the
libraries to be built with the 'w' suffix (eg libncursesw.so,
libmenuw.so, etc), so we need to create a few symlinks.
