[Buildroot] [git commit] luarocks: allow to work with host-luainterpreter

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=513b1b9b7525a4444637210148fd58350a223cc2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

when we embed luajit on target,
we use luarocks with host-luajit instead of host-lua,
in order to use the same interpreter on the both side.
