5.4. Build Flags

We will need to setup target specific flags for the compiler and linker:

export BUILD32="-mabi=32"
export BUILDN32="-mabi=n32"
export BUILD64="-mabi=64"

Let's add the build flags to ~/.bashrc to prevent issues if we stop and come back later:

cat >> ~/.bashrc << EOF
export BUILD32="${BUILD32}"
export BUILDN32="${BUILDN32}"
export BUILD64="${BUILD64}"
EOF
