Run more ld tests when not native

Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only.  Even
when a test needs to run, it's good to compile and link to exercise
the linker.  So that's what this patch does.  I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup.  It's
much simpler to just link with $CC.

This does mean that a cross build with cross-compiler installed but
no cross C-library will give lots of failures.  If that turns out to
be too annoying, I guess we can write a tcl procedure to detect it and
not run all the extra tests.
