|     Override the default build_clib behaviour to do the following:
 | |
| 
 | |
|     1. Implement a rudimentary timestamp-based dependency system
 | |
|        so 'compile()' doesn't run every time.
 | |
|     2. Add more keys to the 'build_info' dictionary:
 | |
|         * obj_deps - specify dependencies for each object compiled.
 | |
|                      this should be a dictionary mapping a key
 | |
|                      with the source filename to a list of
 | |
|                      dependencies. Use an empty string for global
 | |
|                      dependencies.
 | |
|         * cflags   - specify a list of additional flags to pass to
 | |
|                      the compiler.
