Hexagon build infrastructure
Add file to default-configs Add hexagon to meson.build Add hexagon to target/meson.build Add target/hexagon/meson.build Change scripts/qemu-binfmt-conf.sh We can build a hexagon-linux-user target and run programs on the Hexagon scalar core. With hexagon-linux-clang installed, "make check-tcg" will pass.
