s-taprop.adb:717:32: "lwp_self" is undefined
s-taprop.adb:856:10: "pthread_attr_setaffinity_np" is undefined (more

I have traced this to the following commit:

* adaint.c: Add function __gnat_lwp_self that retrieves the LWP of the
current thread.
* s-osinte-linux.ads: Import the __gnat_lwp_self function as lwp_self
* s-taprop-linux.adb (Enter_Task): Store the LWP in the TCB

The function __gnat_lwp_self exists in adaint.c only #if defined(linux),
so it may not apply to kfreebsd-*. The problem exists because
kfreebsd-* uses s-osinte-kfreebsd-gnu.ads, which does not import the
function, but also uses s-taprop-linux.adb, which does use the function.
I am not sure what to do: either introduce a new file
s-taprop-kfreebsd-gnu.adb or provide the function __gnat_lwp_self also
on kfreebsd-* and import it in s-osinte-kfreebsd-gnu.ads.
