bug version: Buildroot-2010.11 (does not exists in version field).

When x86_64/generic (Crosstool-NG toolchain, glibc) architecture is chosen 
compiled executables expect to have pure 64 bit libs in lib64 :

/src/buildroot-2010.11$ ldd output/target/bin/bash
        linux-vdso.so.1 =>  (0x00007fff50fff000)
        libncurses.so.5 => /lib/libncurses.so.5 (0x00007fe7f6c2b000)
        libdl.so.2 => /lib/libdl.so.2 (0x00007fe7f6a27000)
        libc.so.6 => /lib/libc.so.6 (0x00007fe7f66d4000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fe7f6e6a000)

ld-linux-x86-64.so.2 is located in /lib.

Need to have a link from lib64 to lib in fs/skeleton :

cd fs/skeleton
ln -s /lib lib64
