[yocto] Need help getting meta-ada going

[Luke A. Guest]

Hi,

Turns out updating this and making it work properly is harder than I
thought. I'm running into symlink recursion errors on the
popular_sysroot task on gcc-cross-arm.

[log]
DEBUG: Shell function sysroot_stage_all finished

The stack trace of python calls that resulted in this exception/failure was:

All, I've done so far is add ",ada" to the "--enable-languages" flag on
configure, and it's creating a symlink to stamp-bits to itself in the
above directory for some reason, causing recursion.

The layer can be grabbed here:

Can anyone help?

Thanks,
Luke.
