I asked Richard Stallman about this, sending him COPYING.RUNTIME from
the latest release 4.7.0 of GCC, and here is his response:

There is nothing in this exception that would permit distribution
of libgcc itself -- as a separate file -- other than under the GPL.

As part of discussing this with Richard, he said that libgcc ought to
allow building it separately, not as part of the whole of GCC, and if
so, only the small libgcc/ subdirectory of the GCC sources needs to be
distributed together with the libgcc DLL. However, trying to build
libgcc alone fails, at least in GCC 4.7.0, the latest official
release.

Therefore, my interpretation was correct, and anyone who distributes a
package that depends on libgcc DLL needs also to distribute the entire
GCC source tarball. Since latest MinGW builds of many GNU libraries
depend on libgcc DLL, any package using those libraries will also
depend on libgcc DLL, and distributing them requires having the GCC
tarball nearby.
