or1k: add .note.GNU-stack section on linux
In the OpenRISC build we get the following warning:
ld: warning: __modsi3_s.o: missing .note.GNU-stack section implies
executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future
version of the linker
Fix this by adding a .note.GNU-stack to indicate the stack does not need to
be
executable for the lib1funcs.
Note, this is also needed for the upcoming glibc 2.41.

* config/or1k/lib1funcs.S: Add .note.GNU-stack section on linux.
