New DLL test added to GCC testsuite

[Nick Clifton]

Hi Guys,

  Now that the gcc_target_object_format proc is available I have
  checked in a new test, that makes use of it, to the gcc compile
  tests.  This test checks that ports that are supposed to be able to
  generate DLLs (ie COFF/PE based ones) can actually parse the
  attributes without complaining. 

Cheers
	Nick

	* compile/dll.c: New test case.  Check that dll attributes
	compile.
	* compile/dll.x: Only support the dll.c test on	ports that
	use the COFF/PE file format.
