Comment (by jmroot):

 Please provide a log or debug output for an affected install. Base sets
 depends_skip_archcheck for compilers it adds as dependencies, provided
 they support the -arch flag. https://github.com/macports/macports-
 base/blob/v2.8.1/src/port1.0/portconfigure.tcl#L1695-L1699

 Testing with a simple test port shows this is working as intended:
 {{{
 % port installed clang-11
 The following ports are currently installed:
   clang-11 @11.1.0_7+defaultlibcxx+emulated_tls (active)
 % port variants
 testport1 has the variants:
    universal: Build for multiple architectures
 % port deps
 Full Name: testport1 @1.1_0
 Build Dependencies:   clang-11
 Library Dependencies: libcxx
 % sudo port -v build +universal
