I looked at the diffoscope outputs you posted and it is noting the
difference in EFL flags
changing from
0x0000000000000018 (BIND_NOW)
to
0x000000000000001e (FLAGS) BIND_NOW
However, in my local build I see that when I enable --enable-new-dtags
than I always get
0x000000000000001e (FLAGS) BIND_NOW
but when I check the glibc builds without the patch then I get flags
to be 0x0000000000000018
So I wonder if we are comparing previously built glibc ( using
binutils without this patch )
with glibc compiled with binutils using this patch.
