Makefile.SH: 'make test' for cross-compilation builds.

Along with the previous commit, this enables us to run 'make test'
on the host and have the tests run on the target. We do this by
calling ./Cross/run ./TEST with -cwd $targetdir/t, and setting its
LD_LIBRARY_PATH to $targetdir, so that libperl.so is found.
