Subject: [PATCH] Initial support for building Finit statically (incomplete)

This patch adresses issue #5.  However, there still remains a few issues
to work around before Finit can be built completely standalone.

    $ make clean all STATIC=1
    LINK    finit
    helpers.o: In function `getgroup':
    helpers.c:(.text+0x10a7): warning: Using 'getgrnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
    helpers.o: In function `getuser':
    helpers.c:(.text+0x108e): warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
    inetd.o: In function `getent':
    inetd.c:(.text+0x127): warning: Using 'getprotobyname' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
    inetd.c:(.text+0xce): warning: Using 'getservbyname' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

The problem is the NSS plugins and similar issues that prevent static
linking when using the above functions.  See issue #5 for more on this.
