Above version of libobjc2 is old, but due to build errors, and runtime errors, I was 
unable to upgrade. However, a new version was released just a few days ago, and that one even builds
and doesn't show runtime errors so far.
I updated one test box, to get these new ld warnings, there are only these left on amd64:

ld: warning: objc_msgSend: missing endbr64
ld: warning: objc_msgSend_fpret: missing endbr64
ld: warning: objc_msgSend_stret: missing endbr64

Which are all the platforms, that need such fix? I see objc_msgSend_fpret for aarch64, arm, 
amd64, i386, mips and riscv64.

Attached patch to update to the new 2.2 release, without any fixes for the missing endbr64.
