   To put it simply, glibc is backward compatible, but not forward compatible.  If we link against a more recent version of glibc, the linker is going to link against the most recent version of a symbol.  Take that binary to a system with an older glibc and your symbols might not resolve because the newer symbols don't exist.  Take a binary build on a system with an older glibc to a system with a newer glibc and it ought to work because glibc carries around the older symbol versions, providing some guarantee of backwards compatibility.  I hope that helps.
