It turns out I missed a couple other problems.  My apologies -- I
messed up.

Here is the follow-up patch I am committing as obvious.  It fixes the
remaining uses of TYPE_FLAGS in the tree.

Also, I didn't realize that the features/ files were generated from XML.
Whoops.  I will send a follow-on patch for this.

While looking at this, I found that --enable-targets=all does not
build.  Is this known?  I'm thinking that in the future I would like
to enable this flag on my patch tester, so I miss fewer potential
problems in the future.  Also I see a few --enable arguments related
to the gdb build in configure (build-warnings, werror,
gdb-build-warnings) ... should I be enabling any of these?

I tested the appended by building with a powerpc target enabled.
