54   may not.  If we are asked to compile position independent code, we
55   always pass -k to the assembler.  If it doesn't recognize it, then
56   it will barf, which probably means that it doesn't know how to
57   assemble PIC code.  This is what we want, since otherwise tools
58   may incorrectly assume we support PIC compilation even if the
59   binutils can't.  */
