Yeah! It really sucks!

Actually I think maybe we should integrate eu-elflint into
/usr/lib/rpm/verify-elf.  It has --gnu-ld flag to stop barking
at binutils semi-bugs, and otherwise it's useful.

$ rpmpeek libcgal-3.5-alt0.M51.1.x86_64.rpm eu-elflint --gnu-ld ./usr/lib64/libCGAL_ImageIO.so.4.0.0      
section [ 2] '.gnu.hash': hash value for symbol 227 in chain for bucket 316 wrong                                    
section [ 2] '.gnu.hash': bitmask does not match names in the hash table
$ rpmpeek /ALT/Sisyphus/files/x86_64/RPMS/libcgal-3.5-alt1.x86_64.rpm eu-elflint --gnu-ld ./usr/lib64/libCGAL_ImageIO.so.4.0.0                                                                                                                   
No errors
$ 

From what I see it's a malformed ELF.
