It is not allocated.

GNU ld supports both allocated and unallocated notes--it just places
them according to their names in the linker script.  gold also
supports both types of notes, although it swiches based on the section
flags rather than the name.

In any case, it doesn't matter too much what GNU ld does, since gold
only emits these notes in executables and shared libraries, not in
object files.
