Yes, we may deprecate some relocs that can reasonably be handled with 
other existing relocs, but it should be possible to detect this by the 
fact that a conforming toolchain will correctly set the E_FLAGS field.  
However, we almost certainly won't be reallocating those that have been in 
use (at least, not in the near future).
