[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=751e58f606ce5e40194ce929d713ccafb1328888
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libidn was compiled before, mutt will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/mutt | grep NEEDED

 0x0000000000000001 (NEEDED)             Shared library: [libc.so.1]
