No tool chain is available to build for platform 'unix_x86' on FreeBSD

I try to build recovery image on FreeBSD and gradle fails with

cd ./tools/Android_boot_image_editor && ./gradlew pack && mv recovery.img.signed ../../recovery-8110.img
Starting a Gradle Daemon (subsequent builds will be faster)

> Configure project :
Active image target: boot.img

> Task :mkbootfs:compileMkbootfsExecutableMkbootfsCpp FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':mkbootfs:compileMkbootfsExecutableMkbootfsCpp'.
> No tool chain is available to build for platform 'unix_x86':
    - Tool chain 'visualCpp' (Visual Studio): Visual Studio is not available on this operating system.
    - Tool chain 'gcc' (GNU GCC): Don't know how to build for platform 'unix_x86'.
    - Tool chain 'clang' (Clang): Don't know how to build for platform 'unix_x86'.

This is probably an upstream gradle/kotlin/whatever issue but I am going to have a look at it
