Because linker paths are normally machine dependent, you can add
them to your fpc.cfg.

About warnings:
The IDE should warn about strange settings after you have
changed them or when someone else uses your package/project the first
time. The latter case is not that easy to find out, so this is not
really implemented.
Just clicking ok when you have not changed a path should not give a
warning.

About ignoring absolute paths:
Wrong search paths is the top reason for frequently asked questions.
That's why the warnings are there and the number of such questions have
dropped since these were added. We should not ignore absolute paths
in general. 

Supressing:
The IDE has a mechanism to not ask questions for periods
of time. For example asking a question only once per 24h or only once
per project or until the IDE is restarted. Maybe
this can be used for this. But I'm not sure about the parameters.
