Dependency tracking, see the GCC 3.x manual.

Automake uses -MT for dependency tracking. But Automake knows many
way to track dependencies, including some that don't use -MT; so I'm
surprized that it choose this mode (called "gcc3") if ccache doesn't
support it.
How do you configure your project to use ccache? Do you tell
./configure that you want to use ccache as the compiler? (you should).
