Pre-NetBSD 1.3, the arm32 port used hardware float instructions and a
floating point kernel emulator. As of 1.3 and beyond, the gcc compiler
defaulted to soft-float, as the majority (all?) the ARM processors have no
hardware float.
The options are useless for Sharks now that gcc defaults to soft-float.

Yes. It works on all platforms, AFAICT, and I've tested alpha, arm32, and
sparc, three different endian/pointer-size arch combinations.
The Shark config file isn't meant to be a GENERIC - that will happen when
the rest of the CATS merging et. al. is complete and the RiscPC `wdc'
conflicts are resolved.

If you own a Shark, you should be.
