[Buildroot] [git commit] libiconv: disable building the preloadable library

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=82cf4f00ac11fb08eff0f39a6c264d75f4ea0817
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We were already removing the preloadable iconv library (that can be
used through LD_PRELOAD to override the C library iconv
implementation) from staging/target, but it was still built. And this
causes issues in static only scenarios, so this patch changes that to
not even build/install the preloadable library.

[Thomas: changed Gustavo's patch to take into the fact that we never
need the preloadable library.]
