-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
