Multilib has caused nothing but problems for me...I have steered away from
it as much as possible. For developers who build for many different targets
I can see the usefulness of it. For developers who target one platform with
one FP type, one CPU, etc...I just don't see the benfit of multilib...am I
missing something?

Why would one want VFP softfloat. I spent some time researching VFP the
other day and I still don't understand why it would/should be used in any
case.

So basically if I get gcc stage 1 to output softfloat by default, then build
glibc with CC="arm-linux-gcc -msoft-float" I *should* end up with a
softfloat libgcc + softfloat glibc?

Thanks for all your help!
