[PATCH 1/5] msi: Build stub files with -Wno-cast-calling-convention.

[Chip Davis]

Clang warns when casting between function pointer types where the
calling conventions differ; this is of course intended to catch bugs
that we ourselves have had to work around. But the casts here are
compatible with what MIDL generates, so there isn't much we can do here
beyond disabling the warning. This is generated code anyway; it should
be expected to work.
