sstate: Make absolute symlinks an error
The current relocation code is broken, at least in the native case. Fixing it would mean trying pass in new data on sstate tasks about the relative positioning of symlinks compared to the sstate relocation paths. Whilst we could do this, right now I'm favouring making this an error and fixing the small number of problematic recipes we have in OE-Core (3). (From OE-Core rev: cf94de4ddee3e5072da8608c9151301fcec02cd0) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
