This is to make sure we get the correct shared library suffix of the target platform. While for example on Darwin it would even work with the hardcoded .so prefix it's IMHO a bit nicer to have the actual native extension. Signed-off-by: aszlig <aszlig@nix.build>

libredirect is an LD_PRELOAD library to intercept and rewrite the paths in

glibc calls based on the value of $NIX_REDIRECTS, a colon-separated list
|
|
of path prefixes to be rewritten, e.g. "/src=/dst:/usr/=/nix/store/".
