That sounds more like libffi is to blame.  Shouldn't it be checking for
(defined(__SOFT_FP__) || defined(__VFP_FP__))?  Or, if you really are
using soft-float, then presumably gcc is to blame for not defining
__SOFT_FP__.

Either way, it seems like whichever package is broken should just be
fixed, rather than trying to work around it with architecture-specific
CFLAGS forcing.  Assuming that the problem is libffi trying to use FPA
instructions #ifndef __SOFT_FP__, then it will break on ARMv5
architectures as well if you happen to be using VFP.
