There is a bug in cross-arm-none-none-eabi/gcc-11.2.0 that causes compilation to fail. The fix is already applied to the latest masked version and can be installed by using the -g [version] command line option for crossdev. This installs cross-arm-none-linux-gnueabi-11.2.1_p20220115 and works just fine. However, later, when I emerge --sync and emerge -DNuq @world, emerge tries to build version 11.2.0 and the bug rears its head: "C compiler cannot create executables." I attempted to unmask the latest version by adding this to /etc/portage/package.accept_keywords: 'cross-arm-linux-gnueabi/gcc * ~* **', but emerge still insists on building 11.2.0 This seems like emerge doesn't know how to deal with crossdev created packages when there is a mask in place. There is probably some voodoo to unmasking the crossarm tool that I don't know. Any help would be greatly appreciated.

Isn't this because you need to put arm-none-linux-gnueabi-gcc in package.accept_keywords instead?
You are correct. There is actually more than one issue though. emerge had reported issues with the world file and told me how to correct it. I have run that every time for a few months now and not thought much of it. But it turns out that my world file contains cross-arm ... gcc and glibc for versions that are not installed and that was confusing me so I added the wrong reference to /etc/portage/package.accept_keywords. Once I added the correct one, as you suggested, the problem seems to have gone away. I'm currently dealing with an unrelated dependency issue that didn't show up until I edited the world file. Python and beets. Thanks for giving me the push I needed to get to the bottom of this.
No problem. FWIW, bug 833357 will fix the build issue in stable.
