branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

parted uses libiconv but doesn't link with it. Add a patch to add it
to LIBADD of the library that uses it. iconv was already checked in
configure.ac, but only if i18n is enabled, so the iconv check is also
added unconditionally in configure.ac.

Also add an optional dependency on libiconv, so it is reproducible.

This was not detected in the autobuilders, since it only occurs when
libiconv exists (otherwise uClibc stubs will be used). libiconv
depends on !BR2_ENABLE_LOCALE and parted depends on BR2_USE_WCHAR. We
don't have such a configuration in the autobuilders.

+Subject: [PATCH] libparted/labels: link with libiconv if needed
+
+gpt.c uses iconv so it should link with it. Otherwise, on platforms
+where libiconv is a separate library, we get a link failure of parted:
+
+    CCLD     parted
+  ../libparted/.libs/libparted.so: undefined reference to `libiconv'
+  ../libparted/.libs/libparted.so: undefined reference to `libiconv_open'
+  ../libparted/.libs/libparted.so: undefined reference to `libiconv_close'
+
+Since iconv functionality is needed unconditionally (not only when
+gettext is enabled), AM_ICONV needs to be added to configure.ac.
