The difference is that .bashrc is global for the the user, where as a
file can be local to each different build area that the user wants to
keep separate.

What we are discussing is session-local configuration vs
directory-tree-local configuration.  At the moment, bitbake uses some of
each, and that's the root of the problem.  The Makefiles are designed to
turn this into directory-tree-local configuration only.
