[jdk17u-dev] RFR: 8306408: Fix the format of several tables in building.md [v2]

[Zdenek Zambersky]

> Backport fixing several tables in `doc/building.md`, so they would display correctly in GitHub. Change set applied almost cleanly to `doc/building.md` (only last table has one more target in original changeset). File `doc/building.html` was regenerated.

Zdenek Zambersky has updated the pull request incrementally with one additional commit since the last revision:

  Regenerated doc/building.html using pandoc created by devkit
