Subject: [PATCH] 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).

Based on the former patch by Thomas Petazzoni.

[Vincent: tweak patch for 0.166]
[Bernd: rebased patch for 0.177]
