Past attempts didn't fail so quickly or for this reason.
This is for amd64. Configure script for x86-gcc2 hybrid consistency failed
apparently because of
something incompatible in the gcc2 part:
collect2: error: ld returned 1 exit status

What does that mean? I set CC to the path to gcc.
It means people don't build on FreeBSD enough :-)
Try this:

We call -ldl for dlopen and other functions with the host tools,
and these seem to exist within libc on FreeBSD
Thanks!

I believe cross-compiling support on FreeBSD has bitrotted from lack of use.
There is even a reference to FreeBSD 8 in haiku/jam/BuildSetup. FreeBSD 8 is
long past end-of-life.
I just made the changes to BuildSetup and will see how/if it goes. But I
wonder why this didn't bite me long before my attempt of last April 21-22.
from Richard Zak:
-ldl is for libdl, and it's a "Linuxism" according to:
https://forums.freebsd.org/threads/usr-bin-ld-cannot-find-ldl.5799/
As for getting Jam to build on FreeBSD, that'll likely take some time and
effort to figure out how to replace libdl, and using Linux would be faster,
I think.
Type of error made me wonder if the cross-build system was messed up and would
not work even on Linux.
But a lot of things seem to work better on Linux than on FreeBSD or NetBSD.
Now I seem unable to access the internet from the newer FreeBSD 12-STABLE and
HEAD, raising big doubts about my future with FreeBSD.
I also wonder what prevents building the cross-tools for x86_gcc2 and x86
hybrid from FreeBSD, and if Linux would do better.

Before sending this message, I tried again with the revisions to BuildSetup,
got the same error:
