from the rust tree, these bits should probably not be there:

-ifneq ($(findstring clang,$(CC_VERSION_TEXT)),)
 include $(srctree)/scripts/Makefile.clang
-endif

So this was on purpose -- we need the Clang flags even in GCC builds
for bindgen. But now there is that `$(error ...)` added there :(

Miguel, does that seem reasonable?

Of course, for today please feel free to apply your fix (i.e. to put
the conditional back to where it was). I will solve it on my side
tomorrow.

Cheers,
Miguel
