To get the version of glibc installed on a linux box, you can just point directly at the libc shared object file and run it. The output will look something like:
chris@snackerjack-lx:/usr/src$ sudo /lib/libc.so.6

chris@snackerjack-lx:/usr/src$ file /lib/libc.so.6
/lib/libc.so.6: symbolic link to `libc-2.3.6.so'
chris@snackerjack-lx:/usr/src$ file /lib/libc-2.3.6.so
/lib/libc-2.3.6.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.0, stripped

The first line there says 'GNU C Library stable release version 2.3.6' this means that the system is running glibc version 2.3.6
