Realise that the libc core can safely call other libc core functions, even if

they're not defined in the core: so putw() can call stdio stuff, for example.
So the earlier concept of pureness isn't necessary. Rename accordingly.

+This directory contains the libc core: functions here may depend on other
+libc functions _only_ (so, no `unistd.h` stuff). Plats don't get to configure
+this, so nothing here should add any overhead if the function isn't linked.
+
+Examples of what goes here:
+
+  - `strcmp()` --- because it's pure code.
+  - `setjmp()` --- in EM, it's portable.
+  - `assert()` --- because it only calls other core functions (`fputs()`
+    and `abort()`).
+
+Examples of what doesn't go here:
+
+  - `malloc()` --- because it calls the `unistd.h` function `sbrk()` (and so a
+    plat might want to swap it out).
+  - stdio --- because it calls the `unistd.h` functions `read()`, `write()`
+    etc.
+  - `signal()` --- because it can't be implemented portably and needs to go
+    in the plat.
