/* The compiler supports PIC code generation, even though the binutils
|
| 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. */
