UNO bridge not fully ABI compliant on ppc64le

[Dan Horák]

Hello,

after quite some debugging the failure in DEC2BIN() function in the
CppunitTest_sc_addin_functions_test on ppc64le we have confirmed that
the UNO bridge isn't fully ABI compliant. For example int32 parameters
are not correctly sign-extended to 64-bit values. Please see
https://bugzilla.redhat.com/show_bug.cgi?id=2237384 for all the details.


        With regards,

                Dan
