[Buildroot] [PATCH v12 01/32] toolchain: add option to copy the gconv libraries

[Bernd Kuhls]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

The gconv libraries are used to translate between different character
sets (charsets).

In (e)glibc they are implemented by the internal implemenation of
iconv, called gconv, and are provided as dlopen-able libraries.

Some packages need them to present text to the user (eg. XBMC Gotham).
