Log Message:
Add support for NetBSD/aarch64 and arm.

This includes patches for third_party/rust/libc 2.43, which requires
hack to overwrite checksum fields in .cargo-checksum.json. These will
become unnecessary if libc >= 2.45 is imported.

For aarch64,

- python locks up randomly when "make configure"; see lib/54017:
http://gnats.netbsd.org/54017

- nodejs randomly(?) crashes sometimes.

However, if you are luckly enough ;-), you will have a working binary.

Bump revision.
