Hmm, so I already have `CMAKE_CXX_COMPILER_TARGET` set this way in
`hexagon-linux-cross.cmake` (I left this cache out of this PR but I could
include it if it's useful).
So omitting `LLVM_DEFAULT_TARGET_TRIPLE` results in the failure below.
```
cmake -G Ninja \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_CMAKE_DIR:PATH=${TOOLCHAIN_LIB} \
-DCMAKE_INSTALL_PREFIX:PATH=${HEX_TOOLS_TARGET_BASE} \
-DCMAKE_CROSSCOMPILING:BOOL=ON \
-DCMAKE_CXX_COMPILER_FORCED:BOOL=ON \
-C ./hexagon-linux-cross.cmake \
-C ./hexagon-linux-runtimes.cmake \
-B ./obj_libs \
-S ./llvm-project/runtimes

But `llvm-project/runtimes/CMakeLists.txt` has this, which I think is how I
determined that I should be using `LLVM_DEFAULT_TARGET_TRIPLE` (or
`LLVM_TARGET_TRIPLE` eventually?).
```
# Host triple is used by tests to check if they are running natively.
include(GetHostTriple)
get_host_triple(LLVM_HOST_TRIPLE)
message(STATUS "LLVM host triple: ${LLVM_HOST_TRIPLE}")
# TODO: We shouldn't be using LLVM_DEFAULT_TARGET_TRIPLE for runtimes since we
# aren't generating code, LLVM_TARGET_TRIPLE is a better fit.
set(LLVM_DEFAULT_TARGET_TRIPLE "${LLVM_HOST_TRIPLE}" CACHE STRING
"Default target for which the runtimes will be built.")
message(STATUS "LLVM default target triple: ${LLVM_DEFAULT_TARGET_TRIPLE}")
set(LLVM_TARGET_TRIPLE "${LLVM_DEFAULT_TARGET_TRIPLE}")
```
