[binutils] Bump binutils to 2.20.1

binutils/bfd/configure.host

 # This file is a shell script that overrides some of the tools and
 # flags used on a host specific basis.
 
 # Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
 # binutils directories (at least), the index to it is also shared.
 # This is that index.  Each configure.in file should source this file
 # in its per-host part.
 
 # This sets the following shell variables:
 #  HDEFINES             host specific compiler options
