generated sources and make

[Erik Joelsson]

Hello,

I would not like to change the behavior of the existing macro since that 
will have complications for many parts of the build. We could perhaps 
extend it into a special version for the intellij generator script. It 
would be possible to figure out which modules have gensrc dirs by 
looking for gensrc/Gensrc-<module>.gmk makefiles, or we could simply 
always add a potential gensrc dir to the configuration for every module. 
It depends on how well Intellij copes with non existing source directories?

The reason building all gensrc has so many dependencies is Graal. They 
require all their module dependencies to have been built before they can 
generate their sources. The rest of gensrc is pretty cheap to build.
