"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:

從 Makefile.pre.in 中的 coverage-lcov 目標開始，檢查報告中顯示的 lcov 和 genhtml 指令。使用 lcov 2.x 執行 make coverage-lcov，然後確認在沒有報告中的選項錯誤和一致性錯誤的情況下產生涵蓋範圍資料和 HTML 報告。
