I removed the 3 debug sections from libgo that were listed on theobjcopy command.

I left in: debug_info, debug_line, debug_abbrev, debug_ranges, anddebug_str in their original form.

What percentage of the total size of .debug sections got removed by
this process?

A problem with that approach is that .debug_info and .debug_abbrevs
sections are large but are almost entirely unnecessary to just get
file/line information.  Unfortunately almost unnecessary is not the
same as completely unnecessary; they can be greatly reduced, but not
completely eliminated.
