# When cross-compiling, or building with a different version of the compiler than
# the default `gcc`, we additionally need to inform the
# build command which toolchain to use. We do this by setting the environment
# variable `{TOOL_CHAIN_TAG}_{TARGET_ARCH}_PREFIX` - in the case above,
# **GCC5_AARCH64_PREFIX**.
# export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-
# using export here at TOP Level does not work, because
# GCC5_$(TARGET_ARCH)_PREFIX gets deleted again for what reason ever
# Therefore it is set right before the build command
