From e7671c2a3be03d790cbc225cd3e784b5434fb5da Mon Sep 17 00:00:00 2001
From: David Bauer <mail@david-bauer.net>

Subject: [PATCH] config: switch to AC_CHECK_LIB
This fixes spurious build-errors on OpenWrt, where the AM_ICONV macro
is undefined while invoking autoconfig. Later in the build, the ICONV
LDOPTIONS are set to @LIBICONV@, failing the build.
