libidn2-2.3.0 fails to build

[jdauthre]

Running the media autobuild, everything goes well until it runs makefile to build this. Attached the logs

Same error here and libidn2 buildlog say Automake is probably too old. Removing build/libidn2-2.3.0 before compilation did not help.

make[2]: Entering directory '/build/libidn2-2.3.0/build-64bit/src'

configure.ac:38: comes from Automake 1.16.1.  You should recreate

Also: #2698

edit: Modify build\media-suite_compile.sh script to a newer libidn2 library, I tried 2.3.3 but 2.3.7 is also available. Hashcode is from sha256sum libidn2-x.x.x.tar.gz output.
After this change libidn2 was fine, my compilation failed on curl but deleting build/curl-git folder fixed that issue. Next one is mediainfo not compiled yet another separate issue..

    if do_pkgConfig "libidn2 = 2.3.3" &&
        do_wget -h f3ac987522c00d33d44b323cae424e2cffcb4c63c6aa6cd1376edacbf1c36eb0 \
