I think a bold, but definitive approach at fixing this problem would be
to never use known environment variables in Guix search paths
specifications.

Instead, we should introduce custom Guix-specific flavors of the same
variables, e.g. GUIX_GI_TYPELIB_PATH.  That's more work (need to write
and maintain patches that add those Guix-specific variables along their
regular flavor), but that'd mean we can set all the variables we want
not worrying about breaking a foreign distribution.

What do you think?
