+This patch adds support for detecting iconv support using autotools
+uclibc does not have iconv implementation inside libc like glibc, therefore
+the existing checks were not sufficient, it worked for glibc but not for
+uclibc. The new patch portably detects the iconv support and adds the
+libiconv to linker cmdline
+
+This patch should be submitted upstream too
