Subject: [PATCH 2/2] cmake: Provide `install_name_tool` stub instead of
 disabling it

When running `enable_language()`, CMake checks the platform-specific
toolchain components, which includes `install_name_tool` for macOS.
We disable this check when cross-compiling on Linux because
`install_name_tool` is not used and our toolchain file does not provide
it.

However, the current workaround has been breaking CMake's assumptions
since commit eb8facd39606e9472f9ff6de40d7caf76767d0da (CMake 4.1.0,
backported to 4.0.5), which causes an error during configuration using
the Ninja generator.

This change fixes this behaviour by providing a stub executable instead
of `install_name_tool`, as we currently do in the depends build
subsystem.
