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.
