Wrap calls to your cross compiler toolchain
Some Makefiles have hard-coded gcc in its configuration, which is unsuitable if you need to do cross compile.
CrossWrapper can redirect calls to gcc to ${HOST}-gcc so that the cross compiler works even with hard-coded Makefiles.
CrossWrapper works on Linux. Make sure that GNU coreutils are installed on your system.
Then type ./activate, followed by your "host" tuple.
It will scan your current $PATH to create wrapper commands. It may take some seconds if you have a lot of commands installed.
It will start a new shell (by default, bash). When you type something like gcc in the new shell, ${HOST}-gcc will be actually invoked.
When you finished, type exit.
CrossWrapper is only intended for hard-coded Makefiles, instead of auto build systems.
This is because Autoconf and CMake tries to execute the built executable during configuration stage.
If you are already inside a CrossWrapper shell, you still need to specify ./configure --host=$HOST for Autoconf, or cmake -DCMAKE_TOOLCHAIN_FILE=$HOST_CONFIG for CMake.
I am not sure how to do that. If you managed to get it work, please contribute to this project by sending a pull request at GitHub.
Use it as your own risk if you want to use CrossWrapper on any other platform than Linux with GCC toolchain and GNU coreutils.
