Log:
Make sure we restrict Linux only IPC calls from being executed
through the FreeBSD ABI. IPC_INFO, SHM_INFO, SHM_STAT were added
specifically for Linux binary support. They are not documented
as being a part of the FreeBSD ABI, also, the structures necessary
for them have been hidden away from the users for a long time.
Also, the Linux ABI layer uses it's own structures to populate the
responses back to the user to ensure that the ABI is consistent.
I think there is a bit more separation work that needs to happen.

Just curious why not make those functions available via FreeBSD API
instead by properly advertising them in the documentation? From my
completely ignorant point of view it should make it easier to port a
software that has been created on Linux, which is always a Good Thing[tm].
