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)
