I wonder if these are also toolchain-related issues.  allnoconfig and
tinyconfig do build fine for me with GCC 6.1.0 and binutils 2.26.20160125.

generic_defconfig requires mkimage of uboot-tools or it will fail like this:

  ITB     arch/mips/boot/vmlinux.gz.itb
"mkimage" command not found - U-Boot images will not be built
arch/mips/boot/Makefile:159: recipe for target 'arch/mips/boot/vmlinux.gz.itb' failed
make[1]: *** [arch/mips/boot/vmlinux.gz.itb] Error 1
arch/mips/Makefile:365: recipe for target 'vmlinux.gz.itb' failed
make: *** [vmlinux.gz.itb] Error 2

ip27_defconfig indeed has a build issue but it's new for 4.9 (commit
3ffc17d8768be705e292ac4c2e3ab1f18dc06047 ("MIPS: Adjust MIPS64 CAC_BASE to
reflect Config.K0")).  And with that patch reverted GCC 6.1.0 blows up with
an internal compilter error:

GCC 6.2.0 dies the same way.

What binutils are you using and can you send me the build errors messages?

Thanks,
