--- Comment #4 from Jack Howarth <howarth.at.gcc at gmail dot com> ---
The issue in configure can be seen with...
mkdir conftest
cd conftest
echo "int f (void) { return 0; }" > conftest.c
clang-3.6 -c conftest.c
mv conftest.o conftest.o.g0
clang-3.6 -c -g conftest.c
mv conftest.o conftest.o.g
../gcc-4.9.3-20150410/contrib/compare-debug conftest.o.g0 conftest.o.g
..which unexpectedly produces...
conftest.o.g0.stripped conftest.o.g.stripped differ: char 433, line 1
stripping off .eh_frame and LTO sections, then retrying
failed to strip off .eh_frame
conftest.o.g0.stripped conftest.o.g.stripped differ: char 433, line 1
