[PATCH][bfd, opcodes] Remove C99 constructs

[Tom de Vries]

Hi,

When doing a gdb build with --enable-targets=all and gcc-4.8, we run into
build errors.

Two of those are in bfd and opcodes, related to using for loop initial
declarations.  This is a C99 construct which is not availabe by default with
gcc-4.8.

Fix this by rewriting into regular for loops.

Build on x86_64-linux.

OK for trunk?

Thanks,
- Tom
