I installed www-apps/nextcloud now multiple times in at least the versions 17.0.0 and 15.0.0 on gentoo-arm64 and i had never any issues running it there, so i suggest to add the keyword ~arm64 to the ebuild, because at moment i have to accept ~* for installing it.
Thanks for testing and report, I will add keyword to current ebuilds
