Reducted test case for vec_muludq() with make
Compiling the PVECLIB project V1.0.4-4 fails unit test (make check) when
compiled with GCC 12 on Fedora 36/37.
Two units test for:
Vector Multiply Unsigned Double Quadword. vec_muludq()
and
Vector Multiply-Add Unsigned Quadword. vec_madduq()
The tests that fail are passing local vector constants to in-lined instants of
these functions.
Current status; the PVECLIB package is blocked for Fedora 37 because it will
not compile with the default GCC-12 compiler.
