Run more ld tests when not native

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.
