objc.exp (objc_target_compile): Revert the '-framework Foundation' flag fix...

[gcc/testsuite/ChangeLog]
2004-06-07  David Ayers  <d.ayers@inode.at>
	    Ziemowit Laski  <zlaski@apple.com>

	* lib/objc.exp (objc_target_compile): Revert the '-framework
	Foundation' flag fix, since bare Darwin does not ship
	with the Foundation framework.
	* objc/execute/next_mapping.h: Provide a local NSConstantString
	@interface and @implementation.
	(objc_constant_string_init): A constructor function, used to
	initialize the NSConstantString meta-class object.
	* objc/execute/string1.m: Include "next_mapping.h" instead of
	<Foundation/NSString.h>.
	* objc/execute/string2.m: Likewise.
	* objc/execute/string3.m: Likewise.
	* objc/execute/string4.m: Likewise.
