QEMU emulation cannot reliably compile Asterisk — gcc's cc1 randomly segfaults, autoconf tests fail non-deterministically, and pjproject's configure crashes. No amount of config.site or retry workarounds can fix fundamental QEMU instability. Switch to cross-compilation: the builder stage always runs natively on the build platform (FROM --platform=$BUILDPLATFORM). For ARM targets, install cross-compiler toolchains (gcc-aarch64-linux-gnu, gcc-arm-linux-gnueabihf) and target-arch dev libraries via Debian multiarch. Configure with --host=$CROSS CC=$CROSS-gcc. QEMU is only used for the runtime stage (apt-get install, no compilation). Key changes: - FROM --platform=$BUILDPLATFORM for native builder execution - Conditional cross-compiler + multiarch library installation - ./configure --host=$CROSS for ARM targets - Cross-aware strip ($CROSS-strip) for binary stripping - Full make -j$(nproc) parallelism (no QEMU throttling needed) - Removed config.site QEMU workarounds (no longer needed) - Removed retry loops (no longer needed) https://claude.ai/code/session_01M7DJEAxrReANcMZ6SjChaG
