commit: https://git.buildroot.net/buildroot/commit/?id=ba015cdf04a2ee33615f346448ac2e92aac3865a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

realpath is missing on oldish distributions, like Debian 7, which is
still used in the wild.

Use readlink instead; that has been available since the dawn of ages now
(well, coreutils had it in 2003).
