Initial patch, currently test compiling, I hope I have enough space. ** Patch added: "external-flags.patch" https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/2073128/+attachment/5812818/+files/external-flags.patch

Note that this also downgrades some security features: .cxx files are compiled with "GNU C++20 13.2.0 -mno-omit-leaf-frame-pointer -mtune=generic -march=x86-64 -g -O2 -std=c++20 -fvisibility=hidden -finput- charset=UTF-8 -fmessage-length=0 -fno-common -fvisibility-inlines- hidden -fPIC -fno-omit-frame-pointer -fstack-protector-strong -fcf- protection=full -fexceptions -fno-enforce-eh-specs -fasynchronous- unwind-tables -fstack-protector-strong -fstack-clash-protection" .cpp files with "GNU C++20 13.2.0 -mtune=generic -march=x86-64 -ggdb2 -O2 -std=c++20 -finput-charset=UTF-8 -fmessage-length=0 -fno-common -fvisibility- inlines-hidden -fvisibility=hidden -fPIC -fasynchronous-unwind-tables -fstack-protector-strong -fstack-clash-protection -fcf-protection" So -fcf-protection=full is downgraded to just strong -fcf-protection Note that this does not include preprocessor flags, only compilation flags.
