[Buildroot] [PATCH] toolchain: fix installing gconv libs with multi-arch toolchain

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

All,

On 2015-02-20 23:05 +0100, Yann E. MORIN spake thusly:
> For a multi-arch toolchain, gconv modules are in a sub-directory named
> after the machine gcc targets. This is the case, for example, for the
> Linaro ARM 2014.09 toolchain, wihch has the gconv modules in (relative
> to the sysroot):
>     /usr/lib/arm-linux-gnueabihf/gconv
> 
> while the Sourcery CodeBench ARM 2014.05 (non-multi-arch) has them in:
>     /usr/lib/gconv
> 
> So, to catter for both cases, search both paths. We want to favour the
> machine-specific gconv modules over potentially existign "genereic"
> ones, so we first search that (if it exists) and fallback to looking in
> the generic location.

Forget about this patch, I mised half of the fix... :-/

Regards,
Yann E. MORIN.
