I found neither string "libc++" nor "libstdc++" in the full build logs
[1]. That log shows all library builds up to and including libassuan
3.0.2. I use Xcode 15.4, which I should have mentioned right away:

  $ xcodebuild -version
  Xcode 15.4
  Build version 15F31d

The same build process succeeds with libassuan 2.5.7 and libgpg-error
1.49, by the way. Bumping these libraries to versions 3.0.2 and 1.50,
respectively, to satisfy the requirements of GnuPG 2.5.0, were the only
changes I made. That leads me to the hypothesis that modifications in
one or both of these libraries are causing problems. The libgpg-error
build works for 1.49 and 1.50, but as mentioned in a previous message I
had to incorporate a small patch.

One can find my complete build process on SourceForge [2].
