58/* The compiler supports PIC code generation, even though the binutils
59   may not.  If we are asked to compile position independent code, we
60   always pass -k to the assembler.  If it doesn't recognize it, then
61   it will barf, which probably means that it doesn't know how to
62   assemble PIC code.  This is what we want, since otherwise tools
63   may incorrectly assume we support PIC compilation even if the
64   binutils can't.  */
