Yes, I think that should be done whenever updating the version of
autotools.

I also just noticed these 1.11 version specifiers that probably should
be updated to 1.15:
./bfd/Makefile.am:AUTOMAKE_OPTIONS = 1.11 no-dist foreign
./gas/Makefile.am:AUTOMAKE_OPTIONS = 1.11 dejagnu foreign no-dist subdir-objects
./gprof/Makefile.am:AUTOMAKE_OPTIONS = 1.11 foreign no-dist no-texinfo.tex info-in-builddir
./opcodes/Makefile.am:AUTOMAKE_OPTIONS = 1.11 foreign no-dist

Andreas has already given the canonical answer, but something like the
following should work too.

cd ~/src/binutils-gdb/bfd && automake-1.15 --foreign doc/Makefile
cd ~/src/binutils-gdb/binutils && automake-1.15 --foreign doc/Makefile
cd ~/src/binutils-gdb/gas && automake-1.15 --foreign doc/Makefile
