I think there was some effort to allow specifying versioned symbols or something along these lines that was inspired by some breakage introduced by a recent glibc, but i don't know where that went.

However the safe and really recommended approach is to link against older libraries (easiest way is to use a VM running an older Linux distro), like with C and C++. Free Pascal is largely self-contained so Free Pascal on an older distro is trivial and even if you have to build from source it is just a couple of commands.
