8aefb66376 Improvements to .section parsing: 
* If we have a M or a G, reject sections without the type
* Only parse the flag specific arguments if we have M or G
* Parse the corresponding arguments for M and G

We ignore the G arguments and flag for now.

6cd76e63f8 Aliases defined with .symver should copy the binding of the symbols they alias. 
Move the existing patching for undefined symbols so that all the patching
is done in the same function.
