Subject: [PATCH] application: add benchmark toolchain makefiles for hightec

Test it like this

hightec toolchain current 0.3.0 version code size still can be
improved

$ cat application/baremetal/benchmark/quick_bench.sh

for case in coremark dhrystone whetstone; do
    pushd $case
    export SIMULATION=1
    //export GDBREMOTE="whss6:23000"
    echo "Build $case for TOOLCHAIN=hightec"
    make TOOLCHAIN=hightec CORE=n300f DOWNLOAD=sram SILENT=1 clean all
    make TOOLCHAIN=hightec CORE=n300f DOWNLOAD=sram SILENT=1 upload
    sleep 10
    echo "Build $case for TOOLCHAIN=nuclei_gnu"
    make TOOLCHAIN=nuclei_gnu CORE=n300f DOWNLOAD=sram SILENT=1 clean all
    make TOOLCHAIN=nuclei_gnu CORE=n300f DOWNLOAD=sram SILENT=1 upload
    sleep 10
    popd
done
