I shall try that right away... Nope, works!

I eventually understood what was going on. Basically, when you run:

    make ti-gfx-extract

under the hood, it's as you did:

    make ti-gfx-source
    make ti-gfx-extract

But -source creates a stamp file. Then -extract would remove the
directory, thus removing the stamp file.

10 When you run make again, the stamp file for the download is missing, so
make tries to download it again (invisible, since we already have the
archive), creates the stamp file, and extract again, which removes the
stamp file.
20 GOTO 10.
