Closes#421.
This patch cleans up and fixes some minor issues with the locale support
section of the toolchain menu.
1. uClibc requires wchar support if locales are enabled, make locale
support select wchar support.
2. Allow purging of locale information even if there is no locale
support in the C library. This cleans up after packages that
install things into /usr/share/locale on the target.
