Why don't you leave the environment variables out of your bashrc, put
them into individual files, and source them when you want to use a
particular build environment?  All the child shells will inherit the
exported environment variables.

There's actually a tool we use in HPC environments to help automate
this kind of behavior, called Environment Modules
<http://modules.sourceforge.net/>.
