Lets suppose I have a simple library (libfancy.a) consisting of only one source 
file:

#include "fancy.h"

#include <string.h>

void fancy_memcpy(const void *src, void *dst, size_t n)
{
    memcpy(dst, src, n);
}

The header file for this library is:

#include <stddef.h>

void fancy_memcpy(const void *src, void *dst, size_t n);

Clearly this library doesn't depend on certain RTEMS or BSP features.  Its only 
dependency is the C library.  Now it would be nice to build this library with 
the GCC options corresponding to the libc.a in the multi-lib directories.  I 
want one libfancy.a in every directory containing a libc.a.
