elfutils: make it possible to only install the libraries 



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.

Add a --{enable,disable}-progs configure option



Add a --{enable,disable}-progs configuration option to elfutils. This

allows to selectively disable the compilation of the elfutils programs

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

useful because the programs are often not needed, and also because

building the programs against uClibc causes several issues (lack of

obstack_printf() in uClibc for example).
