enable Hexagon target from cmake
This patch allows us to use cmake to specify a cross compiler for Hexagon.
In particular, the patch adds a missing case for the target Hexagon in
cmake/config-ix.cmake, and it moves LLVM_DEFAULT_TARGET_TRIPLE and TARGET_TRIPLE
variables from cmake/config-ix.cmake to the toplevel CMakeLists.txt to make them
available at configure time. Here is the command line that I have used to test
my patches:
$ cmake -G Ninja -D BUILD_SHARED_LIBS:BOOL=ON -D LLVM_TARGETS_TO_BUILD:STRING=Hexagon -D TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_TARGET_ARCH:STRING=hexagon-unknown-linux-gnu -D LLVM_ENABLE_PIC:BOOL=OFF ..
$ ninja check
