# Check toolchain version using the output of xtensa-esp32-elf-gcc --version command.
# The output normally looks as follows
# xtensa-esp32-elf-gcc (crosstool-NG crosstool-ng-1.22.0-59-ga194053) 4.8.5
# xtensa-esp32-elf-gcc (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a) 5.2.0
# The part in brackets is extracted into TOOLCHAIN_COMMIT_DESC variable,
# the part after the brackets is extracted into TOOLCHAIN_GCC_VER.
