You're mixing /lib/ld-linux.so.2 which is hardcoded into every binary
with another libdl.so.2 which isn't hardcoded:

glibc 2.1 has:
$ nm /lib/ld-linux.so.2 |grep _dl_global_scope_end

but glibc 2.0.7 uses:
$ nm /usr/glibc/glibc-2.0.7/lib/ld-linux.so.2 |grep _dl_global_scope_end
0000b54c D _dl_global_scope_end
