First success with this Command...

./release.sh galileo small lte eur

Working Linaro Toolchain seems this:

gcc-linaro-6.2.1-2016.11-x86_64_aarch64-linux-gnu.tar.xz

Later more...

Best Regards

Edit 1.

According to release.sh... you can look inside this shell script...

IMHO:

./release.sh galileo large	SM-R800_NA_USA
./release.sh galileo large lte na	SM-R805U_NA_USA
./release.sh galileo large lte kor	SM-R805N_KOR_SKC
./release.sh galileo large lte eur	SM-R805F_EUR_XX
./release.sh galileo large lte chn	SM-R8050_CHN_CHN
./release.sh galileo small	SM-R810_NA_USA
./release.sh galileo small lte na	SM-R815U_NA_USA
./release.sh galileo small lte kor	SM-R815N_KOR_SKC
./release.sh galileo small lte eur	SM-R815F_EUR_XX

Edit 1.

sudo apt-get install openjdk-9-jre-headless
