PR binutils/22875: FRV/ELF: Prevent an out-of-bounds howto table access
Prevent an out-of-bounds `elf32_frv_howto_table' table access in `frv_info_to_howto_rela' by using the size of the table rather than R_FRV_max to determine the number of entries in the contiguous regular FRV relocation range defined and described in the table. bfd/ * elf32-frv.c (frv_info_to_howto_rela): Correct the range check for `elf32_frv_howto_table' table access.
