description:
make(1): run lint with strict bool mode

The make code is not supposed to use constructs such as "if (strcmp(s1,
s2))" or "if (p && *p)", instead all boolean expressions have a form
that would be accepted by a C#, Go or Java compiler as well.  This also
ensures that pre-C99 compilers generate equivalent code as C99
compilers, at least regarding boolean expressions.
