           Summary: Use BR toolchain externally results a non-bootable
                    root filesystem
           Product: buildroot
           Version: 2014.05
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: xxiao8 at fosiao.com
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


To reproduce(I used IMX6 board)
1. set HOST_DIR to wherever you want to relocate the toolchain.
2. make toolchain
3. build a rootfs using the above-built toolchain _externally_.
4. boot it up, you will find error saying "no init is found"

To fix it manually we need add a ld-linux.so.3 symlink under /lib on the rootfs
1. cd output/target/lib
2. ln -s ld-linux-armhf.so.3 ld-linux.so.3
3. boot with the modified rootfs

If we use internal buildroot toolchain directly, the ld-linux.so.3 is there. If
we use external buildroot toolchain, the ld-linux.so.3 was not created somehow.
