 Attempting to build libgit2 fails:
 {{{

 Digging deeper, it fails at exactly this part of the build process:
 {{{
 cd
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_libgit2/libgit2/work/build/tests/libgit2
 && /opt/local/bin/cmake -E cmake_link_script
 CMakeFiles/libgit2_tests.dir/link.txt --verbose=ON
 }}}

 I tried manually adding variations of `-l /opt/local/lib/libiconv.dylib`
 (`-l libiconv.dylib`, `-l libiconv`) to
 `CMakeFiles/libgit2_tests.dir/link.txt` without success:
 {{{
 /opt/local/bin/cmake -E cmake_link_script
 CMakeFiles/libgit2_tests.dir/link.txt --verbose=ON -v
 ld: library '/opt/local/lib/libiconv.dylib' not found
 }}}
 This one is quite surprising, because libiconv is installed on my system:
 {{{
 $ port installed libiconv
 The following ports are currently installed:
   libiconv @1.17_0+universal (active)
 $ file /opt/local/lib/libiconv.*
 /opt/local/lib/libiconv.2.dylib: Mach-O universal binary with 2
 architectures: [x86_64:\012- Mach-O 64-bit x86_64 dynamically linked
 shared library, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|NO_REEXPORTED_DYLIBS>]
 [\012- arm64:\012- Mach-O 64-bit arm64 dynamically linked shared library,
 flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|NO_REEXPORTED_DYLIBS>]
 /opt/local/lib/libiconv.a:       Mach-O universal binary with 2

 arm64:\012- current ar archive random library]
 /opt/local/lib/libiconv.dylib:   symbolic link to libiconv.2.dylib
 }}}

 I thought it might be related to the recent change
 [abd25f7f4a164c7ab2a8a8146fcbd746f45035a0/macports-ports], reverting that
 commit didn't seem to affect anything.
