Pointers welcome.

Rebuilding gcc will only help for statically compiled packages from this point though, so it seems like a suitably low priority issue there. > > > I've also built binary packages for mipsel and placed them in > > > fencepost.gnu.org:~mhw/binutils-metad/ > > > > Fencepost.gnu.org/~mhw/binutils-metad/ offers me a bin, is that > > expected? > > I'm not sure I understand the question, but if you're asking whether I > intentionally included mipsel binary packages in that directory, the > answer is yes.
