libffi limitation causes bad behavior in JNI on Sparc

On Sparc, libffi doesn't handle integer return types of size 8 or 16.
This causes problems for JNI calls like CallBooleanMethod because the
return value is in the wrong bits of the returned integer. 
For example, a hack that worked for me was to change ffi_call in
libffi/src/sparc/ffi.c to check for FFI_TYPE_UINT8 and FFI_TYPE_SINT8
and do a *(unsigned *)rvalue << = 24 in that case.
