Yes, there is nothing new there - when this configuration was in the gcc/
directory the target name was also the same for both builds. What is new
is that you can now put tests in libgcc/configure.ac such as the "Check
32bit or 64bit for x86." one, and select t-* files based on those tests -
whereas in the gcc/ directory there is no possibility at all for the
choice of t-* files to depend on the multilib.
