I see EM_RISCV added added (by myself, amusingly, as part of a bulk merge) in 2016,
included in glibc 2.24.
From repology, vs our oldest supported OS,
centos stream 8: 2.28
debian 11: 2.31
fedora 39: 2.37
opensuse leap 15: 2.28
ubuntu 20.04: 2.31
So unless there's some *other* symbol you require, all supported OS will have EM_RISCV.
