[Buildroot] [git commit] bash: always prefix readline

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=7a95111e48f5fe387f592463effa233834c6fda1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Always prefix the readline directory otherwise autodetection may pick up
the host readline when headers are available and target == host (or are
link-compatible). Fixes:
