#62944: grpc: py-grpcio port build failures for arm

Component:  ports    |    Version:
 Keywords:  arm      |       Port:  grpc py-grpcio
---------------------+----------------------------
 Some rather, well, interesting build errors, are occurring on our ARM
 buildbot:

 {{{
 [...]
 clang: error: no such file or directory: '"C"'
 clang: error: no such file or directory: '__attribute__((visibility'
 clang: error: no such file or directory: '("default")))'
 clang: error: no such file or directory: 'PyObject*'
 clang: error: clangno such file or directory: '("default")))': error: no
 such file or directory: '("default")))'
 [...etc...]
 }}}

 That's from this example, for `py39-grpcio`:
 https://build.macports.org/builders/ports-
 11_arm64-builder/builds/20741/steps/install-port/logs/stdio

 Full log also attached; filename: py39-grpcio-buildbot-failure-arm.txt.gz

 Is it possible that we have a bug in one of our portgroups?
