Add link path in kincfile.js

[Mavhod]

I make a project from linux target, and I want to add my static lib.

I add some code in kincfile.js like this: project.addLib( "../../../path/to/libxxx.a" );

in makefile from generated will have code like this: -l/absolute/path/libxxx.a

And it build failed because -l is only for library name, so it would have to set path (-L) in kincfile.js, but it seems to have no any way to do it.
