Maybe.
Some ioctls are defined by particular standards or common practices,
so that many UNIX and Unix-like systems support them, and porting is
thus trivial.
Others are not so fortunate. There are many ioctls that are private
to various implementations, that are specific to particular drivers,
and that vary in subtle ways between systems.

They're different platforms and there's no common agreed-on standard
that specifies what _all_ ioctls must do.

No, that's not the reason.
In general, at least for the properly-written drivers, the kernel's
STRUCT_DECL(9f) facility makes certain that 32-bit and 64-bit
applications both work fine on a 64-bit kernel. It adapts
automatically.
