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 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).
