This is interesting.  This is the debugging information for crt0.s. 
It points to the right place in the .debug_line section, but it
doesn't have DW_AT_low_pc and DW_AT_high_pc attributes like the other
compilation units.

What do you get when you run 'readelf -wil' on crt0.o itself?  The
addresses will be meaningless because they haven't been relocated, but
we should be able to see the rest of the information.
