[Buildroot] A 64 bit system which enables 32 bit applications

[Mau Z]

Thanks
Is there anybody out there that had tried to implement something like
this and can advise ?
What If I build both pure systems and simply copy the /lib from the
"pure 32 bits system" to something like /lib32 of the "pure 64 bit
system" ?

Thanks again
