The output now differs from what GNU readelf/objdump generates. There is a tool in yocto which processes `SONAME` entry to detect the name of the shared object and now that test fails and several packages fail when using llvm-readelf, I wonder if there are more such tools post processing ELF files, they all will have similar issues.
