This issue afects binaryes using the sysv style hash table
(-WL,hash-style=sysv)
When the "nbuckets" filed in the hash table (.hash) is set to 0, ldelf
will do out-of-bounds indexing and crash with a data abort. Such a hash
table is strange but GCC 13.3.0 seems to produce them in some cases
anyway.
This fix returns an error is nbuckets is 0 before using the value, and
makes an affected S-EL0 SP binary load fine.
