Yes, you need a very recent version of sparse.

I was oging to hold off that sparse upgrade requirement for 5.9, but
we had independent reasons to just say "gcc 4.9", and at that point
the code that allowed old versions of sparse to work was entirely dead
outside of sparse.

Sparse is really easy to build and install as a regular user. Just do

mkdir -p ~/src ; cd ~/src
git clone git://
cd sparse
make && make install

and it will install the sparse binaries in your ~/bin directory. No
need to be root, it just works.
