qemu-arm: Enable software floating point support, and float tests.

Browse Source 
This helps to test floating point code on Cortex-M hardware.

As part of this patch the link-time-optimisation was disabled because it
wasn't compatible with software FP support.  In particular, the linker
could not find the __aeabi_f2d, __aeabi_d2f etc functions even though they
were provided by lib/libm/math.c.
