Akim Demaille f7b642cff7 build: fix incorrect dependencies
Commit af000bab11 ("doc: work around
Texinfo 6.7 bug"), published in 3.4.91, added a dependency on the
"all" target.

This is a super bad idea, since "make all" will run this
target *before* "all", which builds bison.  It turns out that this new
dependency actually needed bison to be built.  So all the regular
process (i) build $(BUILT_SOURCES) and then (ii) build bison, was
wrecked since some of the $(BUILT_SOURCES) depended on bison...

It was "easy" to see in the logs of "make V=1" because we were
building bison files (such as src/files.o) *before* displaying the
banner for "all-recursive".  With this fix, we finally get again the
proper sequence:

    rm -f examples/c/reccalc/scan.stamp examples/c/reccalc/scan.stamp.tmp
    /opt/local/libexec/gnubin/mkdir -p examples/c/reccalc
    touch examples/c/reccalc/scan.stamp.tmp
    flex   -oexamples/c/reccalc/scan.c --header=examples/c/reccalc/scan.h ./examples/c/reccalc/scan.l
    mv examples/c/reccalc/scan.stamp.tmp examples/c/reccalc/scan.stamp
    rm -f lib/fcntl.h-t lib/fcntl.h && \
    { echo '/* DO NOT EDIT! GENERATED AUTOMATICALLY! */'; \
      ...
    } > lib/fcntl.h-t && \
    mv lib/fcntl.h-t lib/fcntl.h
    ...
    mv -f lib/alloca.h-t lib/alloca.h
    make  all-recursive

* doc/local.mk (all): Rename as...
(all-local): this.
So that we don't compete with BUILT_SOURCES.

# Some of our targets (cross-options.texi, bison.1) use "bison --help".
# Since we want to ship the generated file to avoid additional
# requirements over the user environment, we used to not depend on
# src/bison itself, but on src/getargs.c and other files. Yet, we
# need "bison --help" to work to make help2man happy, so we used to
# include "make src/bison" in the commands. Then we may have a
# problem with concurrent builds, since one make might be aiming one
# of its jobs at compiling src/bison, and another job at generating
# the man page. If the latter is faster than the former, then we have
# two makes that concurrently try to compile src/bison. Doomed to
# failure.
#
# As a simple scheme to get our way out, make a stamp file,
# bison.help, which contains --version then --help. This file can
# depend on bison, which ensures its correctness. But update it
# *only* if needed (content changes). This way, we avoid useless
# compilations of cross-options.texi and bison.1. At the cost of
# repeated builds of bison.help.
