ld/

	* ld.h (ld_config_type): Add rpath_separator.
	* ldmain.c (main): Initialize it.
	* lexsup.c (parse_args): Honor config.rpath_separator.
	* emultempl/elf32.em (gld${EMULATION_NAME}_search_needed): Likewise.
	(gld${EMULATION_NAME}_add_sysroot): Likewise.
	(gld${EMULATION_NAME}_parse_ld_so_conf): Use config.rpath_separator
	rather than ':' when building the path.
	* emultempl/vxworks.em (vxworks_before_parse): New function.
	Override config.rpath_separator.
	(LDEMUL_AFTER_OPEN): Do not change if EXTRA_EM_FILE has been
	set to gld${EMULATION_NAME}_after_open; #define that identifier
	to vxworks_foo instead.
	(LDEMUL_BEFORE_PARSE): Override in the same way as LDEMUL_AFTER_OPEN.

ld/testsuite/
	* ld-vxworks/rpath-1.s, ld-vxworks/rpath-1.d,
	* ld-vxworks/vxworks.exp: New files.
