Subject: [PATCH] Add compatibility libraries and update package dependencies
 for PortMaster

- Introduced portmaster-compat-libs package to aggregate compatibility libraries.
- Added compat-codec2, compat-x264, and compat-x265 packages for multimedia support.
- Updated package.mk files to include new dependencies and improve installation scripts.
- Enhanced start_portmaster.sh to handle mod_ArchR.txt for modular support.
- Adjusted ffmpeg configuration to enable ffmpeg and ffprobe without ffplay.

+Subject: [PATCH] codec2_native: compilar generate_codebook direto com host cc
+
+codec2 0.9.2 usa ExternalProject_Add(codec2_native) para construir uma copia
+nativa de `generate_codebook` durante cross-compile. Sem CMAKE_ARGS explicitos
+a sub-build herda CMAKE_TOOLCHAIN_FILE/CFLAGS/CXXFLAGS do parent (aarch64) e
+falha (compilador cc do host nao aceita -mabi=lp64 / -mno-outline-atomics).
+
+Substituimos o build CMake por um single-shot `cc -O2 -lm`, que compila o
+gerador no host sem nenhuma heranca de toolchain.
