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.

tests/make: test detection of static library files

make(1): use consistent order in .OODATE in test archive.mk

make(1): make individual targets in test archive.mk visible

This test still fails on FreeBSD, printing the "ar cru, ranlib" lines
twice, and I don't know why.

To get more insights into the inner details, without activating the full
-dA logging, split the output into paragraphs, one per target.

This change reveals another interesting detail: Dependencies without any
commands (in this case create-archive) don't inherit the commands from
.USEBEFORE and .USE sources.

make(1): fix expected file for archive test

This test is currently disabled, therefore it didn't fail immediately.

make(1): in archive test, use wildcard that matches more than 1 file

This is to make sure that the buffer used for "archive(member)" is
properly reset after each member.

make(1): add test for wildcards in archive dependency

make(1): fix archive test

At the beginning of that test, the library archive obviously does not
exist yet.

This test failure is a bit hard to detect since the test is disabled in
usr.bin/make, but not in tests/usr.bin/make.  This is because the latter
just runs all .mk files as tests, no matter whether they are commented
out or not.

make(1): add very basic test for archive handling

The whole code in arch.c had been uncovered by tests before.

The code coverage shows that neither the archive name nor the member
contain any $, even though archive.mk looks like it.  It could be
necessary to place the variable assignments below the dependency line,
to force late evaluation.
