I just reproduced it on a third system and see the same issue.  It's an
ancient 32-bit SPARC Solaris 10 system with a bunch of not-quite-so-old GNU
tools under /usr/local/gnu):

hart <at> pogo> m4 --version | head -1
m4 (GNU M4) 1.4.16
hart <at> pogo> libtool --version | head -1
libtool (GNU libtool) 2.4.2
hart <at> pogo> autoconf --version | head -1
autoconf (GNU Autoconf) 2.71
hart <at> pogo> autoconf --version | head -1
autoconf (GNU Autoconf) 2.71
hart <at> pogo> /usr/local/gnu/bin/automake --version | head -1
automake (GNU automake) 1.16.5
hart <at> pogo> $HOME/usr/local/bin/automake --version | head -1
automake (GNU automake) 1.16.92
hart <at> pogo>

Repro steps

# wget https://davehart.net/ntp/test/ntp-4.2.8p18-vcs.tar.xz
# tar xf *p18-vcs*xz
# cd *vcs
# ./bootstrap

Works fine with 1.16.5 in /usr/local/gnu/bin, breaks with
$HOME/usr/local/bin earlier on $PATH

It might be something about the libevent configure.ac or Makefille.am, the
source tree has projects nested three deep:

configure.ac
sntp/configure.ac
sntp/libevent/configure.ac

If you are willing to spend some time, I'm guessing you could reproduce the
failure.  Thanks for taking an interest.

Cheers,
Dave Hart
