v2013.10 based. ;-)

Yeah, slightly down with GCC 7.0.1, but not much:

  LD      spl/u-boot-spl
mipsel-suse-linux-ld.bfd: u-boot-spl section `.data' will not fit in
region `.sram'
mipsel-suse-linux-ld.bfd: region `.sram' overflowed by 264 bytes
../scripts/Makefile.spl:304: recipe for target 'spl/u-boot-spl' failed
make[2]: *** [spl/u-boot-spl] Error 1
/home/andreas/OBS/u-boot/Makefile:1342: recipe for target
'spl/u-boot-spl' failed
make[1]: *** [spl/u-boot-spl] Error 2
make[1]: Leaving directory '/home/andreas/OBS/u-boot/ci20'
Makefile:150: recipe for target 'sub-make' failed
make: *** [sub-make] Error 2
