Build fails on aarch64

[bavier]

Hello Ao,

When I try to build Ao "ao-guile-repl" branch on aarch64 the build fails in the efsw directory with an error from inotify_nosys.h, saying "Unsupported architecture!"

The following patch fixes this. Please forward to the efsw devs.

Hi @bavier !

efsw is maintained here and I'm sure they'd appreciate your patch.

I'm no longer maintaining the ao-guile-repl branch, but if you open up a PR with these changes, I'll merge it in.
