Libunwind and libgcc on ia64

[Mariusz Mazur]

On ia64 libgcc.so is linked to libunwind.so, which means (a) libgcc requires 
libunwind and (b) anything linking dynamically against libgcc doesn't need to 
know or care about libuniwnd.
That changes if one tries to link statically (like my glibc) - then the build 
system must explicitly check what gcc we're running and if it's the libunwind 
one - add -lunwind.
Wouldn't it be a lot nicer if libgcc.a contained libunwind.a? People wouldn't 
have to care about explicit support for ia64.
