 indeed build for arm64... perhaps I'm missing something?

 I just tried to build rust 1.51.0 on arm64 and it still fails. I will
 attach the main.log so that you can take a look.

 I again cleaned up some universal binaries and now glib2 +x11 and libffi
 are arm64 only.

 As already stated I need the openssl at 1.0 as universal binary for
 Powershell. So if this breaks the build I'm fine with it.

 However I can confirm that rust 1.50 did indeed install fine on my M1
 MacBookPro.

 Would it help if I update rustc to 1.51 in the portfile? Is a sudo port
 clean rust sufficient or should I clean some directories manually?
