elfutils: make it possible to only install the libraries

Browse Source 
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.

This option tells elfutils to not only install the libelf
libraries, but also the elfutils programs.

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).
