Functions marked with __attribute__((__constructor__)) will be
invoked in linker order. In theory this is well defined, but
in practice, it is hard to determine what this order will be
with the layers of indirection through meson, ninja and the
static libraries QEMU builds.
Notably, the order currently appears different between Linux
and Windows (as tested with Wine on Linux). This can cause
problems when certain QEMU constructors have a dependancy on
other QEMU constructors.
To address this define a QEMU_CONSTRUCTOR_EARLY constant which
provides a priority value that will run before other default
constructors. This is to be used for QEMU constructors that
are themselves self-contained, but may be relied upon by other
constructors.
