Thomas Petazzoni 8e6c06fb11 elfutils: towards uClibc support: argp-standalone usage
elfutils uses the argp family of functions, that isn't available in
uClibc. So, we add a dependency on argp-standalone if building with
uClibc, and modify elfutils source code to link against argp if
needed.

Heavily based from work done by Stefan Fröberg, but with many further
modifications by Thomas Petazzoni.

Allow the usage of an external implementation of the argp functions
uClibc lack the argp family of functions that glibc has. Therefore, we
add a check in the configure script to see if argp_parse is available
in the C library. If not, we look if it is available in the additional
'argp' library. If so, we link against that library. If not, we error
out.
This allows to build elfutils against uClibc with an external argp
library.
