Yes, a lot of. Like this:
readelf: Warning: There is a hole [0xab1ea0 - 0xab2551] in .debug_loc section.
readelf: Warning: There is an overlap [0xab25ab - 0xab1ea0] in .debug_loc sectio
n.

I'm afraid I will need to remove whole debug info in order to remove this
proprietary info. 
I suppose, it is possible to generate such an ELF using GCC. I've described the
conditions it has to meet.

Maybe. Though, I believe it is also useless to pass the pointer above this
section. I think this value is not used at all except handling
DW_AT_abstract_origin.
