Varargs differ between sysv and ms abi. On x86_64 we have to follow the ms abi though, so we also need to make sure we use x86_64 varargs helpers.
This patch introduces generic efi vararg helpers that adhere to the respective EFI ABI. That way we can deal with them properly from efi loader code and properly interpret variable arguments.
This fixes the InstallMultipleProtocolInterfaces tests in the efi selftests on x86_64 for me.

I thought this was a bug in gcc. Should we include this workaround only for older gcc versions?
