Remove support for 32-bit S390

As discussed in the mailing list thread starting at
<https://lists.freedesktop.org/archives/libreoffice/2023-January/089808.html>
"Plan to remove dead C++ UNO bridge implementations (bridges/source/cpp_uno/*)",
the bridge implementation at bridges/source/cpp_uno/gcc3_linux_s390 is
apparently dead and should thus be removed.  However, that was the only bridge
implementation for 32-bit S390, which implies that support for the 32-bit S390
architecture as a whole is dead and should thus be removed.
