PR binutils/22875: IQ2000/ELF: Prevent an out-of-bounds howto table access
Prevent an out-of-bounds `iq2000_elf_howto_table' table access in
`iq2000_info_to_howto_rela' by using the size of the table rather than
R_IQ2000_max to determine the number of entries in the contiguous
regular IQ2000 relocation range defined and described in the table.
bfd/
* elf32-iq2000.c (iq2000_info_to_howto_rela): Correct the range
check for `iq2000_elf_howto_table' table access.
