No, ~/.zprofile does not need to be made executable.

The config.guess from July 2020 works fine as well.
Not all older released tarballs are affected by this problem. Yes, the
older config.guess returns 'arm-apple-darwin20.3.0' instead of
'aarch64-apple-darwin20.3.0'. But for many packages (including those that
use libtool to install shared libraries) the $host_cpu does not matter.
6. There is no way to do interactive debugging, AFAICS:
* lldb refuses interactive debugging:
(lldb) run
error: process exited with status -1 (developer mode is not enabled on this
machine and this is a non-interactive debug session.)
* gdb is not installed, and if it were installed, it would require
that you use 'sudo gdb' instead of 'gdb' — which of course is not
appropriate on a shared machine in the compilefarm.
See also [1]. (Btw, the attack description [2] would apply to Linux and
*BSD platforms as well.)
