Controlling the glibc version

On Linux we would very much like to control which glibc version we link with. The reason we are ISV and would like to make sure that our libraries works on as many platforms as possible. And also to know on which platforms it does not work so we can tell customers.

After reading the excellent blog http://www.trevorpounds.com/blog/ and doing a lot expirimentation with gcc we concluded that it is almost impossible to get gcc to pick up another glibc version that the one installed as the default on the system. Therefore, it is very important to control which system the released code is build on.
