This is really weird. config.log shows:

configure:18771: checking for iconv.h
configure:18771: gcc -c -g2 -O2 -march=native -fPIC -pthread
-I/home/jwalton/tmp/ok2delete/include -DNDEBUG conftest.c >&5
configure:18771: $? = 0
configure:18771: result: yes

And then later during config tests:

| #define HAVE_ICONV_H 1

I am not sure why the libiconv config goes astray later on.
