+(in which case only the libraries are built and installed). This is

Add and use a --{enable,disable}-progs configuration option to selectively enable or disable the elfutils programs. Generally, on an embedded system, the libraries are more useful than the programs, and being able to not build the programs will make it easier to build the elfutils libraries on uClibc.
