Re: rdynamic? Re: ProjectCenter running or building

[David Chisnall]

-rdynamic is fine.  This means put all symbols on the dynamic symbol table.  
The problem is -r, which means do a partial link.  Some linkers do too much of 
one and prevent the final link from correctly placing everything in the correct 
sections.
