Comment:

 Ok, the main.log says the problem is:

 {{{
 projects/compiler-
 rt/lib/sanitizer_common/sanitizer_platform_limits_posix.cc:169:31: error:
 invalid application of 'sizeof' to an incomplete type 'struct stat64'
   unsigned struct_stat64_sz = sizeof(struct stat64);
                               ^     ~~~~~~~~~~~~~~~

 }}}

 I haven't seen this before, but I see that you are trying to build a 3-way
 universal binary for arm64, i386 and x86_64, which you may be the first
 person to attempt, so it's not surprising you may run into some issues.
 32-bit is dead as of macOS 10.15, so I suggest removing i386 from your
 universal_archs in macports.conf.
