I think we normally use underscores for these names.  Not sure though.

Can you put a comment above this describing what this target does?  (Seems like
it's a dependency of anything that wants to link to gnome-keyring directly or
something...)

Done.

It turns out this type actually doesn't exist in gyp, but it succeeds due to a
bug in the make generator!  I have been trying to remove it.  Can you use 'none'
instead?

So, I changed this, and then the unit tests stopped linking with unknown symbol
errors for the symbols I'm using from libgnomekeyring. Changing it back and
forth toggled the errors, so apparently this does have some effect and 'none' is
not the same.
