After removing your cross compile prefix, with your config I get:

| kernel/bounds.c:1:0: error: -mcall-aixdesc incompatible with -mabi=elfv2

Are you building ppc64, little endian, ELF ABIv2 ?
Is your cross compiler working properly?

I'm compiling natively on that platform (faster for me than an x86 ;-)

4.1.0-rc8 config attached.
