Please add a comment that this linker settings forces the generation of a link
library.

Should we perhaps add the same for the dart_no_snapshot target below?

[Ivan Posva, 2012/03/07 07:22:51]

The dart_no_snapshot target is not shipped as part of the SDK and is generally
only used during development of the VM. In particular during development of
first stages of loading sources. Just avoid the complication of creating link
library.
