remove -m64 compiler flag for non-x86-64 CPU architectures in SIONlib 1.7.7 easyconfigs

[bedroge]

This flag is not supported for (many) other CPU architectures, e.g. on Arm64 it will throw errors like:

gcc: error: unrecognized command-line option -m64

It may even be fine to remove it for x86-64 as well, since it only seems to be useful when cross-compiling for a 64-bit machine on a 32-bit machine?

@boegelbot please test @ generoso

It may even be fine to remove it for x86-64 as well, since it only seems to be useful when cross-compiling for a 64-bit machine on a 32-bit machine?

I asked around and got the following answer:

As far as I'm aware, it should be. As they say, it's mostly only relevant for cross-compiling. I think it's fine to accept.
