The native (host) libclc build was broken at multiple layers; fixed:
1. native_libclc.cmake used literal ${COOKBOOK_SYSROOT} in a single-quoted
heredoc -> CMake saw it empty -> /bin/clang-21. Use $ENV{...} so CMake reads
the env at configure time.
2. Pointed the host compiler at the SYSROOT clang (a Redox-target binary, can't
run on the host). Use $ENV{COOKBOOK_TOOLCHAIN}/bin/clang-21 (host clang,
defaults to x86_64-unknown-linux-gnu).
3. The cross-env restore (LDFLAGS with Redox -L paths + --static) ran BEFORE the
native cmake/ninja, polluting the host link. Moved it to AFTER the build.
4. -DLLVM_DIR overrode the toolchain file with the Redox sysroot LLVM. Point it
at ${COOKBOOK_TOOLCHAIN}.
Compiler detection now passes ('skipped'/OK). REMAINING structural blocker:
find_package(LLVM) loads the toolchain's LLVMExports.cmake but that references
LLVM dev files not shipped in the runtime toolchain -> needs a complete HOST
LLVM dev tree (llvm21 host dev output) for the libclc host build.
