1. Install Toolchain on debian testing(currently bulleseye)
# apt install libnewlib-dev libstdc++-arm-none-eabi-newlib libnewlib-arm-none-eabi gcc-arm-none-eabi binutils-arm-none-eabi
1.2. Verify the version of installed gcc
# arm-none-eabi-gcc --version
arm-none-eabi-gcc (15:7-2018-q2-6+b1) 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907]

At "$(SDK_ROOT)/components/toolchain/gcc" under SDK, there are several kinds of Makefile for Windows/Linux/MacOs.
Now, we should edit "Makefile.posix" in the case of Linux or MacOs like the below.
GNU_INSTALL_ROOT ?= /usr/local/gcc-arm-none-eabi-7-2018-q2-update/bin/
GNU_VERSION ?= 7.3.1
GNU_PREFIX ?= arm-none-eabi
into
GNU_INSTALL_ROOT ?= /usr/bin/
GNU_VERSION ?= 7.3.1
GNU_PREFIX ?= arm-none-eabi
2.1. Try to compile the example.
Under "$(SDK_ROOT)/examples/peripheral/blinkyPCA10056/blank/armgcc",
$ make
mkdir _build
cd _build && mkdir nrf52840_xxaa
