Running with gdb, it looks like the problem comes from the
ppc_closure.S file of the libffi/src/powerpc directory, at line 32 :
Maybe something like:

#ifndef _SOFT_FLOAT
stfd %f1, 48(%r1)
#endif

but then, you might have to have something like:
#define CPP_SPEC \
"%{msoft-float: -D_SOFT_FLOAT} \
(picked at random from lynx.h) in the .h file for your port.

:-) But I'm sure there would be more work to do.

FWIW the backend already does this in rs6000-c.c :)
