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
