enable-target=all would sort of create a single toolchain for multlibs we have but it needs to package the gcc runtime and building glibc accordingly I cant say it will be just harmless to enable it right now mips/powerpc/x86 are architectures that could do it in oe. > > I've been successfully using this patch to generate a complete x86 32bit > distro with a 64bit Xen hypervisor (I believe the result would have been > the same if I tried to compile a 64bit linux kernel).
