Not that I am aware of at the moment. Does next-20200709 work? Does
Linus' tree work? The only obvious thing I can think of is commit
6ec4476ac825 ("Raise gcc version requirement to 4.9")
The commmit message says:
Using _Generic also means that you will need to have a very recent
version of 'sparse', but thats easy to build yourself, and much less of
a hassle than some old gcc version can be.
