Modified Files:
        src/libexec/ld.elf_so: rtld.h symbol.c

Log Message:
The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bu and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:
