At the end of the day, here is what I did:
1) create a development Centos 5.5 machine
2) on the dev machine, I compiled gcc 4.9.3 from sources, installed it
locally and updated the build system (cmake, etc..) with only local
builds, if possible from source. By exploiting LD_LIBRARY_PATH, I link
to the glibc et al. in the gcc 4.9.3 installation path
3) I run Cmake on the dev machine, to obtain the executables and libraries
4) I prepare a distribution with the Cmake-built exe and libs, and in
case of dynamic linking, the dependecies found by ldd
5) I unpack the distribution on my target Cento0S 5.5 machine and run
the execs, if needed using LD_LIBRARY_PATH for the local libs
Quite the workaround, but it works better than manually handling all
glibc dependencies!

I'll try and see if I can compile a gcc 4.9.3 chain on the CentOS
5 machine (I need C++11).
I'd suggest using the devtollset repo from
https://people.centos.org/tru/devtools/devtools.repo
The docker container looks interesting but I haven't used it yet:
does it need some specific install on the target machine? I don't
have any install rights on the Cento 5.11 machine....
I think you misunderstand. I meant to use a docker container on your
Ubuntu machine running CentOS 5 as a development environment. That
way you can use your Ubuntu workstation to build in a CentOS 5
environment.
