I wouldn't do that myself ... but a lot of internal and external
highly respected project does this (e.g. Arduino does this too).

I will look into it ... the thing is there again some inconsistency I
observed (maybe due to my limited understanding) when scons does the
expansion of variables. e.g. if I set OBJSUFFIX to "${CC}.o", it picks
up CC=gcc. However if I set OBJSUFFIX to "${SOURCE}.o", it will not
pick up ${SOURCE} as the file name (it is empty string). So I really
want to understand this behavior a little bit better.
