Thanks for raising this topic.


Both these concrete proposals fail to support the (corner) case of a 
package using 2 build systems simultaneously, only one of them 
supporting parallel builds.

I suggest adding the options DEB_MAKE_BUILD-OPTIONS, 
DEB_MAKE_INSTALL_OPTIONS, DEB_MAKE_CHECK_OPTIONS and 
DEB_MAKE_CLEAN_OPTIONS.

all of those options would be blank by default (to ensure backwards 
compatibility for packages not supporting parallel build). In a next 
major version of cdbs we can enable parallelism by default.
