Yes, that's what I was suggesting.

Not specifying optimisation options explicitely by a user (which would 
otherwise overwrite the default settings) should always yield in a valid 
set of compiler options to successfully build a configuration and run 
the executable. Currently this is broken on Damiana; it needs to be 
fixed in the known-architectures file for Linux.
