Comment (by ryandesign@…):

 Answering my own question, using `[get_canonical_archflags]` in
 `configure.cxx` results in a build failure:

 {{{
 configure: error: C++ preprocessor "/lib/cpp" fails sanity check
 }}}

 Checking config.log, the reason is:

 {{{
 clang: error: cannot use 'c++-cpp-output' output with multiple -arch
 options
 }}}

 which causes configure to try to fall back on other cpps, such as
 /lib/cpp, which doesn't exist.
