Stop building open-vm-tools for LINUX systems with glibc < 2.12.

Implemented a check for glibc version and abort if the detected
version is lesser than 2.12 (This affects RHEL5 and older generations).

Implemented a config switch '--disable-glibc-check', which when specified,
will skip checking for compatible glibc version.

Modified the tools-pkg.make file to specify --disable-glibc-check
while executing "./configure" for open-vm-tools.

Note: glibc check is done only for Linux systems.
