I'd left ILP32 out since it's already mentioned in the Caveats section:
<li>In the AArch64 port, support for ILP32 (<code>-mabi=ilp32</code>) has
been deprecated and will be removed in a future release.
</li>
But I agree that the removal of the multilibs makes it worth a second
mention here. (And also in case people interested in AArch64 don't
read the general Caveats section.)
How about:
<li>As noted above, support for ILP32 (<code>-mabi=ilp32</code>)
has been deprecated and will be removed in a future release.
<code>aarch64*-elf</code> targets no longer build the ILP32 multilibs.
</li>
Thanks,
Richard
