After this fixing building patch, xtensa can pass allmodconfig. - There are still several warnings for it (I sent several patches for them, but not for all).
- Xtensa gcc5 cross compiler has issues: it causes more than 10 broken areas with allmodconfig (but no issues with defconfig). I guess, in fact, it is only 1 real issue (which can cause all breaks), and I shall try to fix it within this month. Welcome any ideas, suggestions, or completions. Thanks.
