Add -B support to gcc-ar/ranlib/nm
To use gcc-{ar,ranlib} for boot strap we need to add a -B option
to the tool. Since ar has weird and unusual argument conventions
implement the code by hand instead of using any libraries.
gcc/:

* file-find.c (add_prefix_begin): Add.
(do_add_prefix): Rename from add_prefix with first argument.
(add_prefix): Add new wrapper.
* file-find.h (add_prefix_begin): Add.
* gcc-ar.c (main): Support -B option.
