ld: Pass --no-rosegment to ld in some linker tests

For elf/x86, --rosegment places code after read-only data, instead of
before read-only data.  Pass --no-rosegment to ld in some linker tests
to avoid extra linker test failures when binutils is configured with
--enable-rosegment for elf/x86.

binutils/

	PR ld/34003
	* testsuite/lib/binutils-common.exp (check_rosegment_support): New.
	(run_dump_test): Make NO_ROSEGMENT_LDFLAGS global.

	compiler.
	* testsuite/ld-x86-64/pr27491-1c.d: Pass --no-rosegment to ld.
