devel/hare: Do not build on arm64

The build on arm64 fails in rt/+freebsd/syscalls.ha, line 246, due to
an assertion failure in faccessat().

The patch added in this update fixes a failed assert in a prior build
phase, since the result of sysctl hw.machine is "arm64" and not
"aarch64" as expected by the unpatched code.

While the patch is not sufficient to complete the build on arm64, it
is committed as a required but not sufficient build fix.

The port revision is bumped because of the update of devel/qbe to
version 1.3.
