Those builds are apparently meant to generate x86-64 binaries, see 
<https://git.libreoffice.org/lode/+/38ea870f6ca4b14e2ab768a82ef09ba3ec878625%5E%21> 
"add host/build flags to autogen job when building on macos-arm64", 
though it beats me how that actually works, given that no traces of the

   --host=x86_64-apple-macos --build=x86_64-apple-macos

from that commit's bin/macosx_clang_dbgutil.env show up in tb86 build 
logs like <https://ci.libreoffice.org/job/gerrit_mac/100772/consoleFull>.
