Build and test for Linux/ARM64

For aarch64 platform, I have built "Lmbench" from source.

## Steps

Following [STEPS](https://github.com/intel/lmbench/blob/master/README) were used for the building and installation:

```

sudo apt update

sudo apt install build-essential cmake git wget -y

git clone https://github.com/intel/lmbench.git

cd lmbench

make -j$(nproc)

```

## Outcome

To validate that the build was successful we ran benchmark using "make result" command. The system benchmarking was completed successfully.

All this information is also added to Software Ecosystem Dashboard for Arm (https://www.arm.com/developer-hub/ecosystem-dashboard/).

Start with the repository README and the reported build commands, then run `make` and `make result` on a Linux ARM64 system. The report says compilation and benchmarking already succeeded, so a useful next step would require identifying a specific repository change or missing ARM64 support target; the issue does not define what completion should mean.
