First some set-up.
This defines the new "git syncsub" command.  Just a shortcut:

  git config --global alias.syncsub 'submodule foreach git pull origin master'

Then run it (in daemon, I presume)

  git syncsub

Then commit that change (presuming it's the only change):

  git commit -m 'build: update gnulib submodule to latest' -a

Then rerun ./autogen.sh ... etc.

(of course you'll want to update the list of modules in
daemon/m4/gnulib-cache.m4 to reflect any additions)
