Follow-up Comment #1:
I pushed a fix. I think it might be possible to do better: one can imagine a
situation where you wouldn't treat the expansion of a variable to put into the
environment as a recursive expansion of a variable used in a recipe. But to
do that would require more work and I couldn't convince myself (or find an
example makefile) where it would make a real difference.
In this change, variables that are recursively expanded into the environment
of a shell function will be set as the empty string rather than throwing an
error.
