It looks like long, float, and double return values are not correct.

It looks like libffi closure support is not working ok.
Check the cls_float, cls_double, cls_ulonglong testcases in libffi. They 
should at least work.

Looks like a ffi problem.

It looks like ffi closures are not really implemented on this platform.

libffi testsuite gives:

<...>
PASS: libffi.call/return_ll.c (test for excess errors)
FAIL: libffi.call/return_ll.c execution test
PASS: libffi.call/return_sc.c (test for excess errors)
PASS: libffi.call/return_sc.c execution test
PASS: libffi.call/return_uc.c (test for excess errors)
PASS: libffi.call/return_uc.c execution test
<...>

I might look into this a little later.
