Usage: reloc-ldflags [OPTION]... HOST LIBRARY_PATH_VALUE INSTALLDIR

Prints a system dependent compiler option for putting a relocatable library
search path into an executable.

The first argument passed to this file is the canonical host specification,
   CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
or
   CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

The second argument is a colon separated list of directories that contain
the libraries at installation time.

The third argument is the directory into which the executable is going to be
installed.

The environment variable LD should be set by the caller.

Options:
      --help           print this help and exit
      --version        print version information and exit

Send patches and bug reports to <bug-gnulib@gnu.org>."
