x86_64-elf-binutils: Don't clutter common directories

GNU info pages for as, ld, etc are linked to common homebrew directories
without any prefix. They may conflict with another instance of binutils
targeting different architecture.

Prefix info pages with package name to avoid brew link conflicts. They
can still be read using info, e.g.:
  $ info x86_64-elf-binutils/as

While at it, disable NLS (Native Language Support). Internationalization
files are linked into shared location and can conflict with another
instance of binutils.
