It's interesting that awk is required. I've been attempting to keep
nbdkit from requiring awk (but we do require sed).
In config.log I see:

configure:5226: checking for gawk
configure:5247: found /usr/bin/gawk
configure:5258: result: gawk
ac_cv_prog_AWK=gawk
AWK='gawk'
but I can't tell where that's coming from ...
Autoconf itself uses awk during ./config.status to generate config.h
from config.h.in, and Automake requires it for 'make check' to support
TAP output. A quick search of the generated configure finds this
telling section:
# We need awk for the "check" target (and possibly the TAP driver). The
# system "awk" is bad on some platforms.
# Always define AMTAR for backward compatibility. Yes, it's still used
I agree that we don't directly use awk in any code we've written, but
GNU tools have long assumed that any Unix-like system has awk
available.
