Stepping down

[Mathieu Lirzin]

Hello,

I will be starting a PhD thesis by the end of the year. While preparing
myself for this new challenge, I feel like my maintainer role for
Automake, Mcron, and Freetalk cannot be fulfilled correctly anymore. As
a consequence I have decided to step down.

Regarding my involvement in the mentoring of the two Automake GSoC
students, I will continue to assume that role until the end of the
summer.

I wish the best for the future of those packages.
