This patchs adds a new metadata kind `exclude` which implies that the global variable should be given the necessary flags during code generation to not be included in the final executable. This is done using the ``SHF_EXCLUDE`` flag on ELF for example. This should make it easier to specify this flag on a variable without needing to explicitly check the section name in the target backend.
