The issue unfortunately isn't old vs. new kernels, just using <linux/*> and
<asm/*> headers, which as can be seen in this case sometimes aren't of a good
quality, kernel treats them as kernel headers and whether they are usable in
userland is far lower priority to them.  So, if <linux/*> or <asm/*> includes
can be avoided, it is always better to avoid them, and in this case it can be
very easily avoided.  And as for disabling whole sanitizer, how would you
expect it to work?  Just let users see a failed bootstrap and then find out
they need to add --disable-target-libsanitizer to configure next time?

OT, Richard, does --disable-target-libsanitizer work for you?
