How to compile without iconv?

I tried to compile git 2.4.3 on Solaris 10. I used the following configuration:

$ ./configure --without-iconv

$ grep -i iconv config.status
ac_cs_config="'--without-iconv'"
  set X /bin/bash './configure'  '--without-iconv'
$ac_configure_extra_args --no-create --no-recursion
OLD_ICONV=UnfortunatelyYes

But when I try to compile it, I get an error that libiconv is missing:

    LINK git-credential-store
Undefined                       first referenced

libiconv                            libgit.a(utf8.o)
ld: fatal: symbol referencing errors. No output written to git-credential-store
collect2: ld returned 1 exit status
gmake: *** [git-credential-store] Error 1

How can I work around this?
