  Those are the buildroot config options you want to modify.

  It's not 100% guaranteed to work for all packages (some packages do explicit
massaging of the CFLAGS passed to them; the Linux kernel is one of them).

  For the -mtune=geode flag, specifically, that should be selected automatically
if you choose geode as the sub-architecture.

  PS: Please avoid posting a full config - do a 'make savedefconfig' and post the
resulting defconfig file.

  Regards,
  Arnout
