This output seems relevant:

That variant of cctools would appear to be not building on BigSur.

It really shouldn't be available to be built on BigSur anyway -- the version from Xcode is newer. I'll look at that.

For now, if you do this:

sudo port -f uninstall cctools
sudo port -v install cctools

you should get the proper one you need, which is cctools +xcode, which is the default for you:

$ port info cctools
cctools @949.0.1 (devel)
Variants:             llvm10, llvm50, llvm60, llvm70, llvm80, llvm90, llvmdev,
                      [+]xcode
