Summary0000910: libiconv detection broken on MacOS for system version
DescriptionThe configure check for detection iconv support looks for a symbol libiconv_close which is present in the GNU libiconv, but not in the iconv support by the Systemlib of Macos (and likely also not in (g)libc).
Workaround is to install a GNU libiconv via macports/fink/homebrew etc.

configure output:
checking for iconv... yes
checking if iconv takes a non-const char**... yes
checking if -liconv is needed... yes
checking for libiconv_close in -liconv... no
checking for libiconv_close in -liconv... (cached) no

excerpt from config.log:
configure:11469: checking for libiconv_close in -liconv
configure:11498: gcc -o conftest -g -O2 -fwrapv -I/usr/inet6/include conftest.c -liconv -lm >&5
Undefined symbols for architecture arm64:
  "_libiconv_close", referenced from:
      _main in conftest-e50b42.o
ld: symbol(s) not found for architecture arm64


The linker fails later resolving any iconv symbols, because no -liconv is passed. (Unfortunately with a quite misleading error message referencing a specific architecture.)

Maybe switch iconv checks to use: https://www.gnu.org/software/gettext/manual/html_node/AM_005fICONV.html
