Repos and licenses are orthogonal, but I get the concern.

Switching gears to other questions:
Should the bootstrap build automatically produce a built-ins library
for each target in "llvm-config --targets-built" or is the developer
expected to provide an explicit list?  Hopefully the former.

Is it reasonable that bootstrap build not depend on GNU binutils?
This might be mission creep, but it's a drag that the unspoken first
step in developing an LLVM based toolchain is "port binutils".  I
haven't kept watch on LLD progress, but perhaps it's far enough along
that bootstrap process can depend on it.
