[bug-mes] mescc arm progress

[Jan Nieuwenhuizen]

Hi Danny,

I have created another wip+wip-arm branch and did some debugging on a
scaleway arm.  Seeing all mes scheme tests pass inspired me to look into
the mes+mescc segfault; that should not happen.  I found that something
weird happens an EOF on arm, not exactly sure what's going on there but
I found a workaround for now.

So, I added two ugly commits on top that now enable mescc to compile run
on mes, with pretty good results:

When you configure --with-courage, make check should continue into the
mes+mescc run.  Usually make check aborts upon the first failure.

Also, --with-cheating now works again; that may help developing the
mescc arm backend.  Now that mes runs, no need to use that during
development.

HTH,
janneke
