Not sure if patchelf is the right tool, but can't hurt to ask/propose a feature:
glibc has symbolic versioning: https://gcc.gnu.org/wiki/SymbolVersioning
It would be great to have a tool that can go through and change the symbolic version of function calls.
This would help in situations where we build against a newer glibc, but actually need the software to run against an older glibc but can't because of pointing to a newer symbolic version.
