From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
Coverage is disabled by default but it is automatically enabled by
bootstrap-configure using --enable-coverage, it creates a new make target
'coverage' that can be run after make check or any tester that produces
.gdca files.
The build time using --enable-coverage is considerable bigger so if
that is a problem just disable it, also this is the reason why it is not
added directly under --enable-maintainer-mode so it is possible to
turn off coverage without having to turn off maintainer mode.
Since lcov apparently cannot detect changes to .gcda there is another
make target 'clean-coverage' so after that make coverage can be
run again.
