There is only one supported way to do what you want.

You need to build against an old sysroot e.g. --sysroot option
in gcc. With the old system root installed in some path to allow
you to compile against it.

It is not supported for you to build against a new glibc
and run against an older runtime. That would be forwards
compatibility, which we don't guarantee.
