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

(all-local): this.
So that we don't compete with BUILT_SOURCES.
