ld: Add tests for -Ur

Test -Ur with __start_SECNAME, __stop_SECNAME, .startof.SECNAME and
.sizeof.SECNAME.  __start_SECNAME and __stop_SECNAME should be defined
to the start and the end of section SECNAME.  .startof.SECNAME and
.sizeof.SECNAME should be undefined.

	* testsuite/ld-elf/sizeof.d: New file.
	* testsuite/ld-elf/sizeof.s: Likewise.
	* testsuite/ld-elf/startof.d: Likewise.
	* testsuite/ld-elf/startof.s: Likewise.
