The glibc-2 that comes with your Linux distribution has them already.
Any official source for glibc contains all the versions of all the symbols.
A symbol with a new GLIBC_2.x version is just added; the old versions
are never removed. The most common case is 'popen'.

readelf --symbols /lib/libc.so.6
Note that there may be multiple libc.so.6: /lib, /lib/mmx, /lib/tls, ...
Check via "ldd ./a.out".

Please be explicit. Name the symbol(s).
