[Buildroot] [git commit] core: sanitize RPATH in target tree before copying the overlay

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=5f4ca518094f7690536074246ab765f36a213783
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We sanitize the RPATH of ELF files in the target tree to deal
with stupid packages that don't correctly use --prefix/DESTDIR
and that end up putting the full absolute build-time directory
in the RPATH.

We do it before copying the overlay and calling the post-build
script. The user is completely responsible for what happens
in the last two steps, and it should never be touched by us.
