Follow-up Comment #8, bug #66085 (group groff):

[comment #7 comment #7:]
> why _shouldn't_ a build use $PATH to resolve command names?

Because essential system commands live in predictable places and are the most
likely to do what's intended.  An aberrant path might not even include /bin at
all, but a robust Makefile need not care.

Now, is that reason enough to bypass the well-established PATH mechanism for
finding executables, and reinvent this part of the wheel within a Makefile? 
Clearly not, according to people who write a ton more Makefiles than I do.
