This seems reasonable, but you need to set up a site.exp similar to that 
set up by "make check", and may need to do other setup that "make check" 
does as well.

For remote host testing to work at all, in practice you need a shared 
filesystem between the build and host systems, located at the same path on 
both, on which both the sources and the directory being used for testing 
can be found.  (There's some testsuite code to attempt to copy files in 
the absence of a shared filesystem, but it's very incomplete.)  The board 
file used for the host may also need to ensure that the working directory 
in which a command is run on the host is the same as the current working 
directory on the build system.
