gen_compile_commands: extract compiler command from a series of commands
The current gen_compile_commands.py assumes that objects are always built by a single command. It makes sense to support cases where objects are built by a series of commands: cmd_<object> := <command1> ; <command2> One use-case is that <command1> is a compiler command, and <command2> an objtool command. It allows *.cmd files to contain an objtool command so that any change in it triggers object rebuilds. If ; appears after the C source file, take the first command.
