Floating-point support for arm is in flux; a lot of people are
using soft-float support because it's noticably faster than
the hardware emulation you're talking about. I know very
little about it, so I'm cc'ing the linux-arm-toolchain folks,
who might know more.
What are your performance requirements? Do you need maximal
speed out of the floating point, or is half fast good enough?
Are you free to use a more recent gcc?
Do you need to interwork with software compiled by others?
