compile issue

[kuzmanzs]

I have following on my path:
/home/me/dev/v2.2.x/ESP8266_NONOS_SDK/tools or ESP8266_RTOS_SDK/tools latest from GitHub
/home/me/dev/1.22.0-100-ge567ec7-5.2.0/xtensa-lx106-elf/bin

and with make COMPILE=gcc BOOT=none APP=0 SPI_SPEED=40 SPI_MODE=QIO SPI_SIZE=1024
getting:

xtensa-lx106-elf-gcc -Os -g -Os -Wpointer-arith -Wundef -Werror -Wl,-EL -fno-inline-functions -nostdlib -mlongcalls -mtext-section-literals  -DICACHE_FLASH   -I include -I ../include -I ../../include -I ../../extra_include -I ../../include/lwip -I ../../include/lwip/ipv4 -I ../../include/lwip/ipv6 -I ../../include/espressif  -o .output/eagle/debug/obj/user_main.o -c user_main.c

EDIT: with ESP8266_RTOS_SDK_V1.4.0 + xtensa-lx106-elf-gcc (crosstool-NG crosstool-ng-1.22.0-88-gde0bdc1) 4.8.5
I got xtensa-lx106-elf/bin/ld: cannot find -lhal:

Which SDK+Toolchain should be used?
