 Can I have:

<https://patchwork.sourceware.org/patch/27910/>
<https://sourceware.org/ml/libc-alpha/2018-06/msg00511.html>

decided for 2.28?  Unfortunately I only discovered it so late in the 
development cycle, because I have only recently dived into addressing 
binutils PR ld/21375 and discovered BZ #23307 in the course.

 The patch blocks the fix for PR ld/21375, and it will probably make no 
sense once we have a release with absolute symbols working (BZ #19818 + BZ 
#23307), but no ABI marking for that.  So I think it's a 2.28-or-never 
change.  The linker-side fix is scheduled for Jan 2019 binutils release.

 Shall I file a separate BZ just for this patch, with the milestone set 
to 2.28?
