Comment (by Gcenx):

 Replying to [comment:11 barracuda156]:
 > Important update: `gcc10-bootstrap` built with `muniversal` (and with
 removed flags as suggested above) is essentially broken. While an earlier
 build ("fake universal") builds `icu` successfully as `+universal`, new
 version ("true universal") FAILS to do the same with the whole list of
 wrong symbols. ''Another 7 hrs wasted, heh.''

 This sounds to me like you’ve not modified {{{icu}}} accordingly to use
 the desired target compiler so naturally it would fail to compile.

 If you want to directly use the compiled {{{gcc}} etc binary’s then build
 for a single arch with multlib/arch enabled instead.


 I’ve got this up and running correctly on my Intel system and m1 Mac mini
 and compiled clang-11-bootstrap as +universal, I’ve checked the arches and
 yet it actually provided i386|x86_64 on Intel and aarch64|x86_64 on my m1
 Mac mini.
