-cov option on Linux creates dependency on _ModuleInfo_6object

[Sean Kelly]

Create any module, build it with -cov, and inspect the asm.  This can 
cause problems if the object module does not have or generate ModuleInfo 
(if it has no unit tests, for example).  I didn't file this in tracker 
because it's another side-effect of the ModuleInfo problems on Linux, 
but I had managed to eliminate all my workarounds before this one popped 
up.  I don't suppose there's anything that can be done about the hard 
extrn dependencies in Linux?  The current state of things feels like 
walking on eggshells at times.
