Add argp implementation
Argp is an advanced support for parsing unix-style argument vectors. In addition to the common getopt interface, it provides automatic response to `--help' and `--version' options and use of custom parser in conjunction with argp native option parser, among others. Argp support is required by elfutils package and prelink. In uClibc argp functionalities has been moved from C library to libuargp.so Further the libc.so linker script contains an AS_NEEDED entry so that it doesn't need to link libuargp.so explicitely. Disable argp test if feature disabled.

+ Argp is an interface for parsing unix-style argument vectors. Unlike
+ the common getopt interface, it provides many advanced features in
+ addition to parsing options, such as automatic output in response to
+ `--help' and `--version' options.
+ A library can export an argp option parser, which programs can easily
+ use in conjunction with their own option parser.
+ A new shared object "libuargp" is created. The "libc.so" linker script
+ contains the AS_NEEDED entry for getting the libuargp linked automatically.
+ Argp support is needed by elfutils libdw.
+
+ Most people can safely answer N.
