[Bug 269369] native-xtools builds for wrong target in releng/13.1

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269369

            Bug ID: 269369
           Summary: native-xtools builds for wrong target in releng/13.1
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: chris@chrullrich.net

In releng/13.1 "make native-xtools" builds a toolchain that targets the host by
default, instead of TARGET/TARGET_ARCH. releng/13.0 works correctly.

Bisecting shows that the first commit that ends up with the wrong default
target is:

    Add WITH_LLVM_BINUTILS to install LLVM binutils instead of Elftoolchain

Reverting this commit as best I can did not fix the bug. Unfortunately the base
build system is far beyond my comprehension.


From releng/13.1:

$ MAKEOBJDIRPREFIX=/usr/obj/aarch64 make -j 4 TARGET=arm64 TARGET_ARCH=aarch64
native-xtools
[...]

I have -j4 build logs from both. If they are needed, please let me know where
to put them (~43 MiB total), and whether I should recreate them without -j, or
with any additional options. The most obvious difference is that the working
(13.0) build has ~3600 more lines in "stage 3: cross tools" and about as many
fewer in "stage 4.2: building libraries" than the broken one.
