"make coverage-lcov" doesn't work with lcov v2.x

Bug report

Bug description:

The Python Developer’s Guide says:

In order to create a HTML report you can install lcov.

Unfortunately, this doesn't work with a modern version of the lcov: e.g. first I got error about missing --path option. It "works for me" (with some warnings) on the patch:

从 Makefile.pre.in 中的 coverage-lcov 目标开始，检查报告中显示的 lcov 和 genhtml 命令。使用 lcov 2.x 运行 make coverage-lcov，然后验证在没有报告中的选项错误和一致性错误的情况下生成覆盖率数据和 HTML 报告。
