There is no such thing as soft VFP.
I can only talk from the requirements of the kernel. gcc 3.4.3 is
the minimum for ARM, which with binutils 2.17 will allow you to build
the kernel as OABI in *any* configuration. No patches required for
either.
Enabling EABI needs a compiler which supports EABI. That's where I
get fuzzy but recent gcc 4 should be suitable. I have had it suggested
to me that EABI support in the toolchain isn't all that stable at the
moment.
As for userspace... and NPTL, that's a different matter.
