Adding target -march=dlx (for DLX) to GCC-3.4.x?

[Anny Blackyew]

I'm using extensively DLX in the development of several simple DLX
programs in Verilog, VHDL, C, Pascal, Oberon-2, ... and in the
construction of different easy compilers targeting DLX.

I need an updated GCC compiler for DLX, preferibly GCC-3.4.x because
it's more easy, stable and less complex than GCC-4.x.

Best regards, Anny Blackyew
