Well, I couldn't find any documentation on what this means, so I 
can't really say.  Does it disable floating point usage 
completely, or does it force software emulation?

There are a couple people in this community interested in 
bringing D to 32-bit microcontrollers. Most of the 32-bit ARM 
Cortex microcontrollers don't have an FPU.  For the few that do, 
here are the attributes in GCC 
(http://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html) needed to 
specify the configuration.

-mfloat-abi=name
-mfpu=name
-mfp16-format=name

But, these are target specific. Since DMD doesn't support any ARM 
platform, I suspect this is irrelevant, but there, you have it 
anyway.
