[Buildroot] [PATCH] package/setools: needs wchar

[Yann E. MORIN]

Even though setools itself does not require wide chars, the configure
script needs them when testing for C99 support.

Since:
  - it is not clear whether wchar are mandatory for C99 or not,
  - only uClibc may miss support for wide chars,
  - using SELinux would probably involve rather big systems (i.e. glibc
    would not be such a huge overhead),
just make setools depend on the toolchain having widechar.

Fixes:
