# Usage:
#   install-reloc library_path_var library_path_value prefix destdir \
#                 compile_command srcdir builddir config_h_dir exeext \
#                 strip_command \
#                 install_command... destprog
# where
#   - library_path_var is the platform dependent runtime library path variable
#   - library_path_value is a colon separated list of directories that contain
#     the libraries at installation time (use this instead of -rpath)
#   - prefix is the base directory at installation time
#   - destdir is a string that is prepended to all file names at installation
#     time; it is already prepended to destprog but not to library_path_value
#     and prefix
#   - compile_command is a C compiler compilation and linking command
#   - srcdir is the directory where to find relocwrapper.c and its dependencies
#   - builddir is the directory where to find built dependencies (namely,
#     alloca.h and stdbool.h)
#   - config_h_dir is the directory where to find config.h
#   - exeext is platform dependent suffix of executables
#   - strip_command is the command for stripping executables, or : if no
#     stripping is desired
#   - install_command is the install command line, excluding the final destprog
#   - destprog is the destination program name
# install-reloc renames destprog to destprog.bin and installs a relocating
# wrapper in the place of destprog.
