Thanks of looking into this. Commit 9591091f1 is quite old, however, and is 
missing a few important xtensa fixes like a20d9fe539 and caee562063. Since 
this breakage is new, It's probably related to the commits pushed to public 
git repo in the last few days. Specifically I suspect 2a021ae81c3 (buildsys: 
update unifdef), but I didn't look too deeply into it.

Can you verify that 3a3ad3dfc1 as default uClibc version for xtensa doesn't 
break the builds? 

BTW, I'd also appreciate your response on 
http://article.gmane.org/gmane.comp.lib.uclibc.buildroot/72570.

Thanks,
baruch
