Comment (by eschnett):

 It turns out that my terminal emulator, and possibly also my shell, were
 {{{x86_64}}} executables running with Rosetta. Maybe this confuses the
 install scripts? I thought that the default system architecture would
 still be {{{arm64}}}, but apparently something was off.

 Anyway, I'm now using a native terminal emulator and a native shell. All
 is working fine, and I was able to install `m4` without problems.

 Thanks for spotting the `i386` clue.
