File build/toolchain/lld.gni (right):

https://codereview.chromium.org/1880873004/diff/20001/build/toolchain/lld.gni...
build/toolchain/lld.gni:8: # Set to true to use lld.
Can you say what lld is? I didn't know and had to look it up.
Just like
  Set to true to use lld, the LLVM linker.

https://codereview.chromium.org/1880873004/diff/20001/build/toolchain/lld.gni...
build/toolchain/lld.gni:10: use_lld = false
Will you need this outside of the windows toolchain setup? If not or if you're
unsure, I think this declare_args should just be moved to the top of that file.
We can always move it out later if we need to share it.

All done, thanks.

(I want to try using lld on linux too "soon", but you're right, I can move this
to a gni then.)
