I'm not sure I understand. It will automagically delete $dest/ccache and then use $home/.ccache ? I'll let the user do the cleanup himself, eventually printing a message that "there's a trailing ccache directory at $dest/ccache" because he may still want to use it later or he made the mistake to change the variable, or whatever. The content may be worth hours of compilation...

not exactly, the default config for ccache is $HOME/.ccache (here it is PRIVATE_CCACHE="no")
with PRIVATE_CCACHE="yes", you can have a ccache folder limited to Armbian tool usage.
Armbian tool creates "root" owned files in $HOME/.ccache (this is somewhat ugly)
I was in trouble ccache-compiling other softwares as "non-root" user so I guess the Armbian tool should clean its own mess
Moreover, (with more changes) it would offer the possibility to create ccache per SoC for mass compilation

... and yes, it will delete $DEST/ccache if it exists when PRIVATE_CCACHE="no" to switch back to $HOME/.ccache
In my opinion, if a tool creates mess (root owned files in $HOME/.ccache) it is better to offer the option to deal/avoid the mess by design (and not by luck/goodwill/etc.) so having a separate folder for ccache is a good option.

OK, I understand the "need" for that cleanup, even if a bit unfortunate...
But untangling the need for running as "root" would be a bigger task, so I retract my objection.
LGTM with the other small glitches fixed...
