SDL's canonical source is now on GitHub. The git commit that matches
the Hg commit we used so far is b13aa509166e, but we switch to the
HEAD of the SDL-1.2 branch, which just has two additional commits
touching the autotools files.

- explain why we don;t use the exactly-maching commit
- use full-length commit hash
- drop the comment: it did not point to the commit we used
