It seems that uname -p returns aarch64c, configfsf.guess uses that, and
configfsf.sub gets confused by that, so it should be reported there. Ah, I
already see at least
https://lists.gnu.org/archive/html/config-patches/2023-08/msg00043.html
so hopefully it will get discussed / solved there.

Hi,
gmp 6.3.0 does not compile on this machine:
zimmerma@cfarm240:~/gmp-6.3.0 $ ./configure
checking build system type... Invalid configuration
'aarch64c-unknown-freebsd14.0': machine 'aarch64c-unknown' not recognized
configure: error: /bin/sh ./config.sub aarch64c-unknown-freebsd14.0 failed
Should I try a specific ABI?

The Compile Farm project is pleased to announce the immediate
availability of cfarm240, an Arm Morello SoC [1] prototype board
running CheriBSD (a FreeBSD derivative).
This system-on-chip research platform [2] features a custom
quad-core aarch64 Neoverse N1-based CPU implementing CHERI [3]
(a memory protection model), and has 32GB system memory. Disk
space is limited (~200GB); be mindful of your resource usage.
We are still in the process of transitioning to our new domain
name and website; please SSH to cfarm240.cfarm.net.
Notes:
* Morello boards are the only physical implementation of this
ISA; lessons learned will be carried to future Arm extensions,
so binary compatibility with Morello is not guaranteed.
* You will want to read about packages [4].
* If you need help with CHERI-specific problems (not Compile
Farm issues), consider joining their Slack [5].
Thank you to the University of Cambridge for hosting
(and developing) this machine!
