* ld.h (args_type): Add field rpath.

Browse source 
* lexsup.c (S_ISDIR): Define if not already defined.
	(parse_args): Add support for -rpath.  If -R is used to name a
	directory, treat it as -rpath for Solaris compatibility.
	* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
	Pass command_line.rpath to bfd_elf32_size_dynamic_sections.
	* ldmain.c (main): Initialize command_line.rpath to NULL.
	* ld.texinfo: Document -rpath option.

Set the name of the dynamic linker. This is only meaningful when

@cindex groups of archives
The @var{archives} should be a list of archive files. They may be
either explicit file names, or @samp{-l} options.
The specified archives are searched repeatedly until no new undefined
references are created. Normally, an archive is searched only once in
the order that it is specified on the command line. If a symbol in that
archive is needed to resolve an undefined symbol referred to by an
object in an archive that appears later on the command line, the linker
would not be able to resolve that reference. By grouping the archives,
they all be searched repeatedly until all possible references are
resolved.
Using this option has a significant performance cost. It is best to use
it only when there are unavoidable circular references between two or
more archives.
