This changes the python generated makefiles

        targets/*/*/Makefile
        targets/*/*/normal/Makefile
        targets/*/*/fallback/Makefile

to use a common copy of romcc, and to leave this compiler untouched by
'make clean' in targets/*/*/fallback/ and targets/*/*/normal/ .
'make clean' in targets/*/*/ will clean romcc.

Thanks to Mats for the initial idea and implementation of a tool to do
this. This patch has almost the same behaviour as the original tool
without having to run the tool each time.
Tested for abuild-friendliness.

The patch saves ~10-12 seconds for every target using romcc. For a full
abuild run, this is ~20% time saved.
For the first 38 abuild targets, total build time is down to 13m24s
instead of 16m22s on my machine.
