 This is a different issue from: https://trac.macports.org/ticket/64769

 I finally have built dependencies as ppc+ppc64 (aside of python310 and its
 modules).
 Thanks to Kencu's advice, I fixed `meson` so that it can now build for
 ppc+ppc64.

 So at first I added `depends_skip_archcheck-append python310 py310-cython`
 to `gobject-introspection` Portfile and tried to build it as `+universal`.
 It failed with the following:

 Then I added `muniversal 1.0` PortGroup and tried to build again. It still
 failed however:

 }}}

 `ppc32` part had this:

 {{{

 WARNING: Cross file does not specify strip binary, result will not be
 stripped.
 WARNING: Cross file does not specify strip binary, result will not be
 stripped.
 }}}

 Now, I made cross-files for `ppc` and `ppc64` by just copying from Kencu
 and replacing arch. For example, original in
 `/opt/local/share/meson/cross` for `i386-darwin` has:

 {{{
 [host_machine]
 system = 'darwin'
 cpu_family = 'x86'
 cpu = 'i386'
 endian = 'little'

 [binaries]
 pkgconfig = '/opt/local/bin/pkg-config'
 cmake = '/opt/local/bin/cmake'
 }}}

 Then my `ppc64-darwin`:

 {{{
 [host_machine]
 system = 'darwin'
 cpu_family = 'ppc64'
 cpu = 'ppc64'
 endian = 'big'

 [binaries]
 pkgconfig = '/opt/local/bin/pkg-config'
 cmake = '/opt/local/bin/cmake'
 }}}

 There was nothing about strip binary there. What did I do wrong and how to
 fix this?
