But I don't think the .rela.debug_info section can be SHF_ALLOC, thus
gdb will have to duplicate symbol resolution from ld.so anyway.
And when it does, I think it is preferable to always use debug info
from the module defining the symbol rather than the one refering to it.
Plus, on REL arches this is incompatible change, since
previously .debug_info section contained address of some variable/function
in the current module while with .rel.debug_info it will have to contain
addend (ie. usually 0).
