toolchain: add option to copy the gconv libraries
The gconv libraries are used to translate between different character sets ('charsets', even 'csets' sometimes). Some packages need them to present text to the user (eg. XBMC Gotham). In (e)glibc they are implemented by the internal implemenation of iconv, called gconv, and are provided as dlopen-able libraries. Note that some gconv modules need extra libraries (shared by more than one gconv module), so we must, when adding a subset of modules, scan the installed modules in search of the missing libraries. [Thomas: add general explanation in expunge-gconv-modules and fix coding style.] Signed-off-by: "Yann E.
