Sorry, mistake caused by tiredness.
The separate install steps were because I couldn't be bothered to
install the YODL suite of tools in that jail, so skipped the doc stages.

I just built zsh on Ubuntu Xenial with PCRE packages from 2:8.38-3.1,
and could not reproduce.
I think the only way to get this failure is if PCRE support wasn't
actually built in, and the pcre module became a stub. Easiest way to
check for that is to look at the HAVE_* values in config.h:
% grep HAVE_PCRE_ config.h
#define HAVE_PCRE_COMPILE 1
#define HAVE_PCRE_EXEC 1
#define HAVE_PCRE_H 1
#define HAVE_PCRE_STUDY 1
The build flow requires that you enable the flag, and that
`pcre-config --version` exits successfully.
Are you missing a build dependency?
If you examine the file `config.log` and look for `pcre` then you should
see what checks the configure system ran and what the results were,
which may help with tracing down when things have gone wrong.
There may still be a bug in zsh, or some failure mode which can be
handled more gracefully, but we'll need to know what's actually failing
first.
Hrm, perhaps `--build-require-all-enables` or something for the
`configure` script could have the build system go "hey, you enabled
PCRE, but I'm not going to enable it for $reasons, so that's a fatal
error". Mechanism: config.h would #define `SHOULD_ERROR_IF_ENABLED` and
`ENABLE_REQUESTED_FOO` for each FOO, and then the #if guard in/around
the relevant modules would just have an `#else if
defined(SHOULD_ERROR_IF_ENABLED) && defined(ENABLE_REQUESTED_FOO)`
followed by `# error whatever` just at the end.
