Which? I could be missing something, but I am not seeing such code in [1].

Correct. libgloss stuff is completely irrelevant wrt RTEMS.

I am seeing one issue with newlib/libc/machine/or1k/setjmp.S

It is not properly licensed. All it carries is this:

+/* Simple setjmp/longjmp for the OpenRISC 1000 (OR32 ISA).
+   Damjan Lampret, OpenCores.org, Aug 15 2000.  */

You'll have to contact a legal copyright holder of this code (I'd guess 
Damjan Lampert or representative of opencores.org) and ask him to (re-) 
license this code under legal terms which are suitable to newlib.
