cannot build openwrt

[w40]

help me, please.
i cannot build openwrt from
https://github.com/OLIMEX/openwrt

1st:
openwrt/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/json-c-0.12/missing automake-1.15 --gnu Makefile
Makefile.am:6: error: Libtool library used but 'LIBTOOL' is undefined
Makefile.am:6:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
Makefile.am:6:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
Makefile.am:6:   If 'LT_INIT' is in 'configure.ac', make sure
Makefile.am:6:   its definition is in aclocal's search path.

i inserted into Makefile.am.inc
LIBTOOL=/usr/bin/libtool --tag=CC

error again:
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'

i run here:
./configure LIBTOOL='/usr/bin/libtool --tag=CC'
hmmm: warning:
./configure: line 4698: AM_PROG_LIBTOOL: command not found

then error:
.libs/arraylist.o: could not read symbols: File in wrong format
collect2: error: ld returned 1 exit status

can anybody help me?
