arguments are concatenated and passed to the runtime linker, which uses

The @code{-rpath} option may also be used on SunOS. By default, on
SunOS, the linker will form a runtime search patch out of all the
@code{-L} options it is given. If a @code{rpath} option is used, the
runtime search path will be formed exclusively using the @code{-rpath}
options, ignoring the @code{-L} options. This can be useful when using
gcc, which adds many @code{-L} options which may be on NFS mounted
filesystems.
