I tried building that tree with my mer SDK and it worked.. I used 
following steps (inside mersdk):

sb2 make sbj_defconfig
sb2 make -j8 zImage
sb2 make -j8 modules

I use my own Jolla sb2 target, but the kernel should pretty much build 
without dependecies. Might be just some tool missing. Check if you have 
following in your SDK target:

BuildRequires:  python
BuildRequires:  pkgconfig(ncurses)
BuildRequires:  perl
BuildRequires:  kmod >= 9
BuildRequires:  fdupes
BuildRequires:  binutils-devel
BuildRequires:  elfutils-devel
BuildRequires:  python-devel
BuildRequires:  flex
BuildRequires:  bison
