 1.5  11-Jan-2025  rillig make: replace "Malformed conditional" with "Variable is undefined"

Evaluating a conditional such as ".if ${UNDEF}" produced a "Malformed
conditional" error, even though the form of the conditional was correct,
it was the content of the variable that was wrong.

Replace this message with the more accurate "Variable is undefined",
revealing which of the possibly many variables is actually undefined.
 1.4  10-Jan-2025  rillig tests/make: test expressions based on undefined variables

When an undefined variable is used in a conditional, make complains about
"Malformed conditional", which is wrong since the conditional is
well-formed but errors out during evaluation.

In order to fix this wrong error message and preserve the remaining
behavior, cover the places in which an expression is evaluated with
undefined expressions being an error (VARE_EVAL_DEFINED), but with
neither producing an error message nor handling errors. This combination
results in the same behavior as evaluating the expressions in the mode
that allows undefined variables to be used in expressions.
 1.3  19-Nov-2023  rillig tests/make: replace 'variable expression' with 'expression'

Each expression is based on a variable, there's no need for the
verbosity. The wording in make's diagnostics will be changed in a
follow-up commit.
 1.2  23-Jan-2022  rillig tests/make: extend test suite, move old tests to 2020 scheme

The tests from envfirst.mk are now in opt-env.mk.
The tests from modword.mk are now in varmod-select-words.mk.
