Support unordered .debug_info references to .debug_ranges

[GoogleCodeExporter]

As Ash <ashutoshkagrawal@gmail.com> reported,

"I am trying to create a shared library. My library gets generated
after the following warning. I have been able to use the library
successfully so far, but I am curious to know if something is wrong,
what does this warning mean and how to resolve this.

---

target SharedLib: libmytest (out/target/product/surf/obj/
SHARED_LIBRARIES/libmytest_intermediates/LINKED/libmytest.so)
target Prelink: libmytest (out/target/product/surf/symbols/system/lib/
libmytest.so)
libelfcopy: Warning: Location lists in .debug_info section aren't in
ascending order!
libelfcopy: Warning: Location offset 0x133d3 from CU 411 is not
preceded by the end of a location list, skipping...
target Strip: libmytest (out/target/product/surf/obj/lib/libmytest.so)
"

Jan Kratochvi mentioned that readelf had the same problem:
"
readelf sometimes complains on valid DWARF already produced by g++-4.3+:

readelf: Error: Range lists in .debug_info section aren't in ascending order!
readelf: Warning: Range lists in .debug_ranges section start at 0x60
"

So, improving libelfcopy might be a proper solution.

Two approaches to resolve:
  - beagle-donut branch
  - latest toolchain with binutils fixes

The both were included.  Fxed

Fixed in binutils, but it occurs in libelfcopy still.  Reopen.
