 * ld.texi (Output Section Data): Document the new directives.
 * testsuite/ld-scripts/asciz.t: Adjust to work on more architectures and to test more aspects of the ASCIZ directive.
 * testsuite/ld-scripts/asciz.d: Adjust to match the changes to the test linker script.
 * testsuite/ld-scripts/ascii.d: New test driver.
 * testsuite/ld-scripts/ascii.s: New test assembler source.
