IMO no. Ideally we should probably check and error out if the compiler
does not support the -f flags, but it seems a bit like overkill (and
might happen indirectly anyway).
That is enough to generate coverage reports.
The Makefile part does require lcov, however that is completely
optional, other people might actually want to use other tools on the
coverage data, so I'm in favour of not requiring lcov.
I'd hope that anyone who cares about coverage data will be able to
figure out what it means when they get a message that lcov was not
found...
