gnu: llvm: Let it cross-compile.
The derivation when compiling natively remains the same, so this doesn't cause any rebuilds. * gnu/packages/llvm.scm (llvm-12)[arguments]<#:configure-flags>: Set LLVM_TABLEGEN, LLVM_DEFAULT_TARGET_TRIPLE, LLVM_TARGET_ARCH and LLVM_TARGETS_TO_BUILD when cross-compiling. Signed-off-by: Mathieu Othacehe <othacehe@gnu.org>
