I don't remember why keywords were dropped for this version, but there is no -arch - so please give it a try and keyword accordingly.
Checking the buglist, perhaps you should have a look at bug #79233
Bug #79233 is definitely the culprit here on SPARC.

Sparc fails, and it fails intentionally as distributed. It is not allowed in the build of xrootd, and unix/src/TUnixSystem.cxx does not know about it. There is detailed information and a strawman patch at https://bugs.gentoo.org/show_bug.cgi?id=87305 (see also Comment #2 from Jason Wever). I have marked this version -sparc to make it explicit that as distributed, it is set up not to work on sparc (xrootd). But as 87305 notes, it is ~sparc-able with a couple changes. Sorry for the cross-ref bugs; I missed this bug when I was generating the sparc-specific one.
Thanks, closing.
