It might be better to do things like this in the get_env function,
where there is a clean mechanism to declare default values for
arbitrary env vars. Some packages set their own CC (and other) env
vars (for example, passing -I or -D flags), settings which would be
lost if you make a blanket assignment. OTOH, some pkgs also use CC to
force use of gcc3, as it is known they do not compile correctly with
gcc3.3...no idea how the IBM compilers' compatibility compares to
gcc's so dunno what compiler you'd want to have these pkgs use.
