# 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.
