[Scons-users] bug with AddOption?

[Gabe Black]

There seems to also be another problem here as well, although this one
might be a usage error on my part. It looks like if you use the --linker
option, you also have to use it in --linker=gold form, and can't use it as
two arguments, ie --linker gold. I think both *should* work, so this might
be another symptom of the first problem.
