[PATCH 1/3] tools: move initial declarations out of 'for' loop

[Masahiro Yamada]

When I was trying to compile this code for hostprogs-y notation of
Kbuild, I was hit by the following error.

  error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode

This is because KBUILD_HOSTCFLAGS specifies -std=gnu89 whereas the tools
Makefile compiles it with -std=gnu99.

Of course, it would be possible to pass -std=gnu99 per file, but it
shouldn't hurt to fix the C code.
