Fix various cross-fixinclude problems

[Geoffrey Keating]

This patch:
- Makes sure that fixinclude/ is built on all targets.  Even if the
  target doesn't want to fix any headers, fixinclude/ should still be
  built, to make sure that the dummy fixincludes can be installed
  (and give a consistent set of installed programs).
- Actually passes the --target switch to the build fixincludes, so
  that when it gets run it can tell whether or not it needs to do
  anything.

Tested by building a cross to powerpc-eabisim (up to the point where
it tries to use the cross-ar on libgcc.a), and by a bootstrap on
powerpc-darwin.
