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.
