- check for required test program (bc) on target in bc-script.sh
However, this test may fail if 'bc' is not present on the target. This test should, in test_run or test_deploy, look to verify that 'bc' is present on the target, and gracefully abort the test with a useful error message.
Added support for optional test_pre_check() in the base script, and function is_on_target() to functions.sh. This allows for a test to check that a particular file or program is on the target system.
