i don't think that's true.  on an x86_64 system, the 64bit libs are in 
/lib64/.  some distros tried to (pointlessly imo) resist and force 64bits into 
/lib/ when the native ABI was x86_64 (Gentoo included), but those are legacy 
imo, and afaik, they didn't break the ldso paths.

so in a setup that only has hardfloat binaries, you'd have all the libs in 
/libhf/, not just the ldso.

the implication in supporting both hardfloat and softfloat simultaneously is 
that you'd could have them both installed.  thus putting them both in /lib/ 
doesn't make much sense if you're still going to need /libhf/ to hold 
everything else.
