So we will need to wait for kernel 4.20 or use a linus tree to actually build
a csky toolchain?

Yes (and use mainline versions of GCC and binutils, not releases, as
well). The rule I documented at
<https://sourceware.org/glibc/wiki/NewPorts> is that those components need
to be upstream first, but only in the current development version, without
needing to be in a release.

Yes. This is how I ran into
https://sourceware.org/bugzilla/show_bug.cgi?id=24022

Wouldn't be useful to add an option to checkout mainline version
of Linux (using linus tree), binutils, and gcc as we do for
glibc itself?

For binutils and gcc it already exists - specify binutils-vcs-mainline and
gcc-vcs-mainline as arguments to the checkout command. Yes, it would be
reasonable to add support for specifying linux-vcs-mainline.

I was thinking in an option as 'checkout vcs-mainline' or
'checkout vcs-mainline-all. I will work on the linux-vcs-mainline.
