Comment (by barracuda156):

 Replying to [comment:3 ryandesign]:
 > 2. universal ppc ppc64 builds fail with `Cannot find specified cross
 file: ppc64-darwin`. This relates to the fact that glib2, along with
 countless other projects, have decided for some reason to switch to the
 immature new meson build system which has some trouble with universal
 builds. See #59864, #62498. I don't have a solution for you. Complain to
 the developers of glib2 for switching to a build system that doesn't work.
 Complain to the developers of meson for introducing a build system that
 doesn't work. If you have a solution, please provide it. Maybe it is as
 simple as creating a "cross file", whatever that is, for ppc64-darwin, if
 you can figure out how and where to do that.

 Thank you for pointing that out, I will try to find a solution re meson.

 As for the first issue, trying to build `icu` as universal asks for
 universal `llvm-3.3`, which fails. I spent this night trying to fix that,
 but no success so far. Link for others' ref:
