On initialisation of the child instance, ./mk is executed, but an error from it won't reveal what command was actually executed. This change makes that the case, since x_ does print the command that caused an error. This is useful for debugging. However, we don't want x_ to cause a real exit, because we still need to handle the lock file from the parent instance. Therefore, the first child instance is executed inside a subshell, and xbmk_rval is set if that subshell returns non-zero. Signed-off-by: Leah Rowe <leah@libreboot.org>
