 Actually, I think at the BR developer meeting we decided that even if there are
binary-only packages that require softfloat, our defconfig should still use
hardfloat if possible (since the defconfig doesn't enable that package). Anyway
the point is moot since those binary packages will in my experience also depend
on glibc, so the defconfig will not work for them anyway. Also, I can't find
this back in the report :-(
