Cleanup cross-compilation

[traversaro]

Before this PR, we were using emulation for linux_aarch64 and linux_ppc64le . As in https://github.com/emscripten-forge/recipes/pull/124 we are trying to understand more what is going on with cross-compilation, it is worth to try to use cross-compilation for for linux_aarch64 and linux_ppc64le, and also understand why cross-compilation is working fine on osx_arm64 .

Exactly like in https://github.com/emscripten-forge/recipes/pull/124, on linux-aarch64 and linux-ppc64le the build is failing because CMake is not able to find Python headers and numpy headers:

For some reason instead on macOS everything is working fine, and CMake is finding Python and NumPy headers in the BUILD_PREFIX:
