Hi,
libffi currently FTBFS on powerpcspe like this:
...

make[2]: *** [all-recursive] Error 1
make[1]: *** [all] Error 2
make: *** [stamp-build] Error 2
...
The codebase supports powerpcspe already, but some recent changes broke it.
Attaching a patch that fixes it via the __NO_FPRS__ conditionals already used
in all the other powerpcspe specific places.
