proposing Sourceware as Software Freedom Conservancy member project

[Christopher Faylor]

Thanks Elena.

In case it isn't clear we're doing this for all of the projects on this page:
https://sourceware.org/projects.html (some of which are defunct, but still).  This isn't just for
the GNU Toolchain projects like binutils, gcc, gdb, and glibc .

We're also interested in hearing from popular projects like cygwin, newlib, and systemtap
