Because I'm tired of hours of compilation of llvm/clang I'm testing

Setup a jail with 13-CURRENT. Compilation of the installed version went

Today I svn up'd and compiled and compilation broke.

I can see the difference between /usr/include/sys/mman.h and
/usr/src/sys/sys/mman.h is exactly about these symbols.
Why is the base compiler using the latter and ports llvm11 the former?
Configuration of my src.conf and make.conf is described in
https://blog.klop.ws/2020/08/waiting-for-clang-forever-and-ever.html .
Do I miss some directive about system header files?
During what stage is this, and is it an incremental (e.g. -DNO_CLEAN)
build? With this kind of failure, it is usually required to be able to
inspect the full buildworld log, and the exact command line you used to
invoke make. If you can, upload that somewhere so it can be viewed.
It is during the building world stage and happens with and without
NO_CLEAN.

That said, it looks like something is messing up your include order,
as during a very early stage in buildword, the sys/sys/ headers are
symlinked to objdir/tmp/legacy/usr/include/sys/. This should include
the mman.h header.

I just added CROSS_TOOLCHAIN=llvm11 to make.conf and src.conf, but no
difference. I think I need something with --sysroot, but am not sure if
this is something I should set or which the build framework should set.
Any advice on this? Or a pointer to the right documentation?
Regards,
Ronald.
