gcc/testsuite/

	* lib/gcc-defs.exp (gcc-set-multilib-library-path): Delete.
	* lib/target-libpath.exp (ld_library_path_vars): New variable.
	(init_ld_library_path_env_vars): New function, replacing the
	orig_*_saved assignments.  Call it after defining it.
	(set_ld_library_path_env_vars): Rewrite to use ld_library_path_vars.
	(restore_ld_library_path_env_vars): Likewise.
	(add_path, find_libgcc_s): New functions.
	* lib/objc.exp (objc_init): Use find_libgcc_s instead of
	gcc-set-multilib-library-path.
	(objc_target_compile): Don't add "." to ld_library_path.
	Use add_path.
	* lib/gfortran.exp (gfortran_link_flags): Don't add "." to
	ld_library_path.  Use add_path.  Use find_libgcc_s instead of
	gcc-set-multilib-library-path.
	* lib/g++.exp (g++_link_flags): Likewise.
	* lib/obj-c++.exp (obj-c++_link_flags): Likewise.
	* lib/c-torture.exp: Do not manipulate ld_library_path at the
	top level; do it...
	(c-torture-execute): ...here instead.  Use $ld_library_path_multilib
	to tell when this needs to happen.  Use find_libgcc_s instead of
	gcc-set-multilib-library-path.
	* lib/gcc-dg.exp: Likewise.
	* lib/gnat.exp (gnat_target_compile): Don't add "." to ld_library_path.
	* g++.dg/compat/compat.exp (alt_ld_library_path): Don't add "."
	unless it is in $ALT_LD_LIBRARY_PATH.
	* g++.dg/compat/struct-layout-1.exp (alt_ld_library_path): Likewise.

libffi/
	* testsuite/lib/libffi-dg.exp (libffi-init): Don't add "."
	to ld_library_path.  Use add_path.  Add just find_libgcc_s
	to ld_library_path, not every libgcc multilib directory.

libgomp/
	* testsuite/lib/libgomp.exp (libgomp_init): Don't add "." to
	ld_library_path.  Use add_path.  Add just find_libgcc_s to
	ld_library_path, not every libgcc multilib directory.
	* testsuite/libgomp.c/c.exp (ld_library_path): Don't call
	gcc-set-multilib-library-path; rely on $always_ld_library_path instead.
	* testsuite/libgomp.c++/c++.exp (ld_library_path): Likewise.
	Use add_path.
	* testsuite/libgomp.fortran/fortran.exp (ld_library_path): Likewise.

libjava/
	* testsuite/lib/libjava.exp (libjava_init): Just add
	find_libgcc_s to libjava_libgcc_s_path, rather than every
	libgcc multilib directory.
	(libjava_arguments): Explain why we add "." to ld_library_path.
	(gcj_invoke, exec_gij, libjava_invoke): Use add_path.

libmudflap/
	* testsuite/lib/libmudflap.exp (libmudflap-init): Don't add "."
	to ld_library_path.  Use add_path.  Add just find_libgcc_s to
	ld_library_path, not every libgcc multilib directory.

libstdc++-v3/
	* testsuite/lib/libstdc++.exp (libstdc++_init): Don't add "."
	to ld_library_path.  Use add_path.  Add just find_libgcc_s to
	ld_library_path, not every libgcc multilib directory.
