[pushed] Darwin: Define a suitable section name for CTF [PR101283]

[Iain Sandoe]

Hi,

This is a placeholder name ahead of any CTF implementation on
LLVM (which sets Darwin ABI).  Ideally, we would get agreement
on this choice (or any replacement) before GCC12 is shipped.

tested on Darwin18,
pushed to master, thanks,
Iain
