gem5 now build with arm64 command.

[EE415-20170470]

I have error on running ./build --arch aarch64 --download-dependencies gem5-buildroot command because gem5 now build with arm64 command!

I also has same error on #143 because I think some environment missed when running only ./build-buildroot -- glibc-reconfigure

Can you try:

sudo apt install liblua5.4-dev

and then check with:

./build-m5 -aA

? The m5 has an annoying dependency on lua I believe.

I can then add to the dependencies if it works.

I think you can just change

        if self.env['arch'] == 'x86_64':
            env['gem5_m5_source_dir_build_arch'] = 'x86'
        else:
            env['gem5_m5_source_dir_build_arch'] = env['arch']

to

        if self.env['arch'] == 'x86_64':
            env['gem5_m5_source_dir_build_arch'] = 'x86'
        elif self.env['arch'] == 'aarch64':
            env['gem5_m5_source_dir_build_arch'] = 'arm64'
        else:
            env['gem5_m5_source_dir_build_arch'] = env['arch']

in common.py.

It solved build error in my case.
