I don't see an explanation why this is desireable to do.

This doesn't work when cross compiling, because the files used at runtime won't be available there. And it most probably can make binaries unportable, in case the files are available in different directories on different machines.

So this is a clear -1 from me for this patch, even if the motivation would be explained.
