Gnulib-related problems building Bison from git

[Paul Eggert]

I can't build Bison from Savannah git. See attached transcript, which ends:

  GEN      lib/inttypes.h
make: *** No rule to make target 'textstyle.h', needed by 'all'.  Stop.

The Makefile (also attached) has a rule to build lib/textstyle.h. 
However, it says "TEXTSTYLE_H = textstyle.h" and "BUILT_SOURCES = ... 
$(TEXTSTYLE_H) ..." and since $(BUILT_SOURCES) is a prerequisite for 
"all" the build fails.

I am building on Ubuntu 21.10, except with bleeding edge Autoconf 
(2.72a.22-6027-dirty) because Bison requires at least Autoconf 2.71.


One other problem that's Bison-specific. Bison's README-hacking.md says 
that I can update to the latest version of all submodules by running the 
command "git submodule update --recursive --remote"; however, that 
doesn't work for me. If I try it, I get this response:

$ git submodule update --recursive --remote
Submodule path 'gnulib': checked out 
'9853d34f27b5b0eed29d28cfba326ddd9b35ea6e'
Submodule path 'submodules/autoconf': checked out 
'b0d5d2d3eb05cf765c44f0499a622a99319d629f'

However, this doesn't actually check out Gnulib commit 
9853d34f27b5b0eed29d28cfba326ddd9b35ea6e; it leaves the old Gnulib 
working files in the Gnulib subdirectory. I am using git 2.32.0.

I tried working around this second problem by running:

git submodule foreach git pull origin master
./bootstrap
./configure
make

However, I got the same results.
