Cross-compile LoongArch with LLVM and a sysroot - #1423
Merged

Conversation
Upstream packages support this platform directly.
Use Clang and lld with a Debian-provided sysroot and GCC runtime objects. Install libcrypt into the sysroot as this was split from glibc.
Use mmdebstrap in a preparation stage to extract target headers and libraries from the Debian Ports snapshot.

Use the bundled llvm and lld with a Debian-provided sysroot and GCC runtime objects. Construct the sysroot using
loong64packages from a debian-ports snapshot, using the pattern that is used for native builds.Remove the LoongArch-specific downloads of config.guess and config.sub. The pinned libxcb and xorgproto releases already recognize loongarch64-unknown-linux-gnu and cross-compile successfully with their bundled scripts.
