The install-reloc script, when creating a wrapper program, compiles a few
selected source files directly. Whereas the program not necessarily needs
these as object files. For example, GNU hello doesn't need an
AC_LIBOBJ([canonicalize-lgpl])
but the install-reloc script compiles canonicalize-lgpl.c.
This leads to a few new autoconf macros. Here is the first one:
