[GCC steering committee] RL78 port maintainership

[DJ Delorie]

I would like to propose myself as the RL78 GCC port maintainer.  The
RL78 GCC port is currently being reviewed, and the corresponding
binutils port has been accepted.  In addition to being the primary
author of this port, I also have RL78 hardware to test against and an
extensive history with Renesas parts in general.

Thanks,
DJ
