#9 ld.so link undefined symbols

[Gregory Nutt]

The ld.so build should link (statically) with libgcc.a.
Now it has some dangling undefined references. These
are normally fixed up when ld.so links with libc.so.

However, there is one test test/hello-nolibc that does
not link with libc. In this case, ld.so warns about
these undefined symbols within itself (although the
test does run successfully)
