I found another use case of an unset PATH variable:
The configure script from mandoc (http://mdocml.bsd.lv/) uses this
interesting approach to query default CC command from make:
CC=`printf "all:\\n\\t@echo \\\$(CC)\\n" | env -i make -sf -`
Why does it `env -i` at all? (And why does it prepend a \ to the output?)
It seems this scriptlet has an issue, rather than adapting core
behaviour for it.
