We have since quite a time the support for creating native executables
on some platforms. This functionality is not tested at all. The Makefile
has just one very simple rule to create a "Hello world"-like program
with "make testexec".

Testing the EXEC core should probably use EXEC_SHARED, but I don't know
if that works. Hopelfully Daniel is listening and can provide some hints.

Takers welcome,

    print "Hello World\n"
    end

Alas, it's hard to create that file portably.  In particular,
        echo 'print "Hello World\n"'
gives different results with different 'echo' commands.  The
default bash behavior is to pass the \n on through.  The default
ksh behavior is to interpolate the \n and replace it by an actual
newline.  Adding the -e flag to bash's echo command forces it to
act like ksh, but ksh complains about the unrecognized -e option.

The symptom of this is the following rather mysterious error message:

    error:imcc:op not found 'print' (print<0>)

    in file 'hello.pasm' line 1

We could use a perl one-liner in place of echo, but getting all the quotes
right across different operating systems is still hard.

This patch takes a simpler approach:  it creates a new file
examples/assembly/hello.pasm, and just uses that.

It still doesn't work on Solaris/SPARC.  I now get

    error:imcc:main: can't produce object file*** Error code 1

but that's to be expected because the code simply isn't written yet to
produce native executables on this platform.

"make testexec" should run like "make testj" i.e. test all ~2000 current
tests via the exec core.
