I finish analysing for it, it is really only one issue for gcc5, and I
guess, this issue is also not only for xtensa. I send related fix patch
to gcc patch mailing list, hope it can pass checking.

The cause is "the variables are not initialized before using them", the
bug information is "";.

After fix this issue, it can build xtensa Linux kernel with allmodconfig
