Comment (by amake):

 I have seen in other ports a problem with the system SDK, wherein a port
 has baked into it a reference to e.g. MacOSX11.0.sdk which no longer
 exists on Big Sur 11.1 (there is only MacOSX.sdk or MacOSX11.1.sdk).

 On a whim I searched the emacs binary for the string `MacOSX11.0.sdk` and
 found that indeed it did have it:

 {{{
 % grep -l -U MacOSX11.0.sdk /opt/local/bin/emacs
 /opt/local/bin/emacs
 }}}

 In fact I did a recursive search on my `$prefix` and found that lots of
 things had the old SDK baked in. One of those things was the glibtool
 binary, which I vaguely thought might be involved in the build process.

 So I force-uninstalled the libtool port and reinstalled from source. Then
 I reinstalled emacs-devel +nativecomp from source as well. (In the process
 coreutils was also built and installed from source.)

 This seems to have fixed my problem.
