unfortunately, trying to hack the link lines won't help with this.  the
headers and libraries are kept in sync.  you can't use newer headers and
try to run against older libraries.

your best bet is probably to just get an older toolchain and use that to
compile.  or get a copy of the distro that's used in production and use
that to compile the code you care about.  distros often can be used in
chroots so it's not like you need to reinstall the entire system.
