description:
make(1): allow to disable debug logging options
This is only intended for the unit tests, to selectively enable and
disable debug logging as needed. Previously the tests for debug logging
required complicated postprocessing that was not obvious when looking at
the test .mk file alone, but was specified externally in
unit-tests/Makefile.
This is the simplest possible implementation. Another variant would
have been to selectively disable individual debug logging options, but
that would have made the code more complicated.
The -dL option is not affected by -d0 since that is not really a debug
option, even if it is implemented as one.
