Ahh right, sorry, I must have misread that as it's quite clear on second
read.

It might be useful, but then again, I'd expect that if as-needed and
no-undefined were used there would be link failures prior to the tests
being built (it bombs out much earlier for me when I do that).

So the link flags would be interesting to see but unless they are
different flags for the tests than for the main build then I'll be a bit
confused....

But then again I make no claims to really understand linking fully :D
