I don't know if this will help, but I created a proper [1]

[1] By proper, I mean based on FreeBSD/ARM64 sysroot (currently
only Release 11.0 available)
Thanks, I will look at it next week. Is there a documentation on how
the toolchain was created, or is it basically along the lines of
normal gcc-based toolchain creation?
The ports makefiles are recipes. If you want to know how something is
built, you look at those. There are many cross-compiler ports in the
tree. The only thing special about this one is that a bootstrap
compiler is used in order to build the Ada front-end. But that's just a
case of specifying it over a base compiler.
Although I somehow would prefer
if I can manage to base my cross-compile toolchain on the base system
toolchain.
Good luck, since that's impossible. Cross-compilers need their own set
of binutils for the target system. You're not going to be able to do
better than what I did.
