Bug: ld segfault in libbdf-2.22-system on latest Debian stable

[Rafael Stahl]

Hello,

after some of our team members set up new virtual machines for 
developing, they were unable to build our project. The build fails, 
because of a crash in binutils.

Our target system is Debian 7.8 arm64.

The strange thing is that the build still works on my virtual machine 
which was an installation of Debian of an earlier version (7.X), but 
this system is fully up-to-date and so reports 7.8 as debian version 
aswell. For testing, I set up a supposedly identical VM and got the 
crash there, too.

Please let me know how I can help resolve this issue. Unfortunately, I 
can not provide you with the input objects to the linker.

=== Details about the crash ===

The minimal invocation command that causes the issue. Two C++ objects 
and two static libraries are linked together. If any one of the four 
components is removed, the command does not crash. The output contains 
file and line of the assert.
