[PATCH] bfd/elf32-or1k: fix building with gcc version < 5

[Giulio Benetti]

Gcc version >= 5 has standard C mode not set to -std=gnu11, so if we use
an old compiler(i.e. gcc 4.9) build fails on:
```
elf32-or1k.c:2251:3: error: 'for' loop initial declarations are only allowed in
C99 or C11 mode
    for (size_t i = 0; i < insn_count; i++)
    ^
```

So let's declare `size_t i` at the top of the function instead of inside
for loop.
