binutils: fix build without texinfo

binutils-2.34/missing: 81: makeinfo: not found
WARNING: 'makeinfo' is missing on your system.
         You should only need it if you modified a '.texi' file, or
         any other file indirectly affecting the aspect of the manual.
         You might want to install the Texinfo package:
         <http://www.gnu.org/software/texinfo/>
         The spurious makeinfo call might also be the consequence of
         using a buggy 'make' (AIX, DU, IRIX), in which case you might
         want to install GNU make:
         <http://www.gnu.org/software/make/>
