t4k_common 0.1.1 fails to link for me on macOS 12 in MacPorts:

make[3]: *** [libt4k_common.la] Error 1

This despite the fact that the configure script has determined how to link with libiconv:

checking for iconv... yes
checking for working iconv... yes
checking how to link with libiconv... -liconv

Yet it has not actually added -liconv to the link flags. If I manually add -liconv to LDFLAGS when configuring then it does link successfully but the build system should do that itself.

To address this, I suggest investigating the build scripts to ensure that the libiconv dependency is correctly detected and incorporated into the build process. By doing so, we can streamline the build process and improve compatibility across different platforms.
