configure: Fix dangling link when --disable-static is specified

Browse source 
If I configure with ./configure --prefix= --enable-shared --disable-static, a
broken symlink lib/libunwind-generic.a is installed that points to a missing
architecture-specific version of that library (e.g. lib/libunwind-x86_64.a). I
suppose that not installing that library is the intended behavior with these
configuration settings, so the symlink should not be there in the first place.
