[Buildroot] [PATCH 1/1] Option to copy Linaro gconv libs to target

[Yann E. MORIN <yann.morin.1998@free.fr>]

Stanislav, All,

On 2013-11-02 22:37 +0100, Stanislav Vasic spake thusly:
> This patch adds an option for external Linaro toolchains
> which allows buildroot to copy gconv libs to target.

We have another, more generic patch in the making:
    http://patchwork.ozlabs.org/patch/357067/

which I'm still working on:
    https://www.gitorious.org/buildroot/buildroot/commit/9a86575442f9861fa5a4777798fc84b999a12f7f

and which should supersed this patch.

As such, I marked this patch superseded in the pathwork.

I haven't seen the need to export GCONV_PATH when running my XBMC,
neither did Maxime.

What is the reason for exporting GCONV_PATH, if the gconv libs are
properly installed in /usr/lib/gconv ?

Is it because Linaro toolchains install them in
libc/usr/lib/arm-linux-gnueabihf/gconv ?
