To be honest, I don't know. The compiler should have been defaulting to
that already so I don't understand why it wasn't working. We now
explictly set this in master to allow for toolchain relocation and the
machine specific sysroots support. You could try backporting the piece
of code I previously referred to which should also fix the problem.

If that option were missing from the toolchain I'd have expected you to
see other errors rather than just this isolated problem...

That all looks reasonable enough...
