2021-04-01hexagon: do not specify Python scripts as inputsPaolo Bonzini
Python scripts are not inputs, and putting them in @INPUT@. This puts requirements on the command line format, keeping all inputs close to the name of the script. Avoid that by not including the script in the command and not in the inputs. Also wrap "PYTHONPATH" usage with "env", since setting the environment this way is not valid under Windows.

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.
