Well, it's not really a "responsibility": most of the Buildroot
contributors are volunteers so there are no obligations. But if you can
give some help from time to time for some SPARC specific issues, that
would be nice.

Have you had some time to look at the toolchain components? As I said
earlier, we are currently keeping gcc 4.4.x only for SPARC Leon, so if
you could test if gcc 4.8.x and/or 4.9.x work fine for Leon, it would
allow us to get rid of the support for gcc 4.4.

See package/gcc/Config.in.host for the details of the gcc versions that
we allow for SPARC Leon.

Thanks a lot!

Thomas
