# Usage:
# install-reloc library_path_var library_path_value prefix compile_command srcdir config_h_dir exeext 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
# - 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
# - 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.
