make: on error, print the targets to be made

This helps to understand situations with several nested sub-makes in
varying directories.

tests/make: force line-based diagnostics to be listed in the tests

This way, contradictions between the intended output and the actual
output are closer together and have a better chance of being spotted.

tests/make: explore edge cases involving .ifmake

make(1): update and add comments in tests

As a result of the new comments, some line numbers have changed in the
output of the tests. No other changes.

make(1): add test to cover the If_Eval call in EvalNotEmpty

make(1): extend test for .ifmake and .MAKEFLAGS

make(1): add test for the .ifmake directive

make(1): add dummies for fine-grained tests, one per single feature

The test names have been derived from the current manual page.

All these tests are dummies right now, and the code from the existing
tests will be moved into the new tests step by step.

This is done to prevent modmisc, escape, varmod-edge and varmisc from
growing without any bounds, and to reduce the side-effects of one test
to the others.
