hey,

just found out that there are 2 broken symlinks in raspi3 images pointing to build env full path. not sure about other embedded. ascii image, inside /lib/modules/4.16.14-v8+, dirs "build" & "source". same in a self-built beowulf image for raspi3 & 4.20 kernel..(see below) not sure if those symlinks should be there at all (?) if they should, maybe replace full path with .arm-sdk/tmp/.../ or something different that's not "pinpointing" to build env details? closer step to making these images reproducible too :)

$ ls -la /lib/modules/4.20.10-v8+/
