So the configure script goes like this:

  if test x$as_have_required = xyes && (eval "$as_suggested") 2>/dev/null;
  then :
  else
    [ ... Almost 100 lines never executed ... ]
  fi
fi
SHELL=${CONFIG_SHELL-/bin/sh}
export SHELL



as_have_required is "yes".
as_suggested is set in multiple consecutive statements:


+ as_suggested=  as_lineno_1=
+ as_suggested=  as_lineno_1=195
+ as_suggested=  as_lineno_1=195 as_lineno_1a=$LINENO
  as_lineno_2=
+ as_suggested=  as_lineno_1=195 as_lineno_1a=$LINENO
  as_lineno_2=196
+ as_suggested=  as_lineno_1=195 as_lineno_1a=$LINENO
  as_lineno_2=196 as_lineno_2a=$LINENO
  eval 'test "x$as_lineno_1'$as_run'" != "x$as_lineno_2'$as_run'" &&
  test "x`expr $as_lineno_1'$as_run' + 1`" = "x$as_lineno_2'$as_run'"' || 
exit 1

  test -n "${ZSH_VERSION+set}${BASH_VERSION+set}" || (

ECHO='\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'
    ECHO=$ECHO$ECHO$ECHO$ECHO$ECHO
    ECHO=$ECHO$ECHO$ECHO$ECHO$ECHO$ECHO
    PATH=/empty FPATH=/empty; export PATH FPATH
    test "X`printf %s $ECHO`" = "X$ECHO" \
      || test "X`print -r -- $ECHO`" = "X$ECHO" ) || exit 1
test $(( 1 + 1 )) = 2 || exit 1
