usage in case PIC generation is on (some by adding PIC-versions of
    the assembler code, most by adding -Cg- to the options to be used).

    Note: the Intel assembler reader does not yet support the Delphi
    PIC construct, so tests with that (like test/tasmread and test/tcg1)
    do not work with -Cg on non-Darwin (Darwin needs a different PIC
    construct)
