Please test: patch that makes the build script work in parallel, improves build time

These patches[1][2] makes it possible to run our build script with the -j parameter, which makes it use more then one process and thus improves build time on multi-core systems. to test, run make -j2 make -j3 or make -j4 (the number is the number of allowed jobs, shouldn't be higher then your number of cores). don't run it with -j without a number, because it will run as many jobs as it can, resulting your machine to become un-responsive until the build is complete (that's was the result on my machine, might differ on others). Also it won't affect if you are building single language, it only improves speed if you build two or more. The second patch fixes a bug that Sijis discovered yesterday with the first patch, related to RSS caching. Don't forget to run make clean before you test. I won't push it before it gets tested properly. One of the reason it requires a lot of testing is that I don't know python and this is the first time I'm editing Makefiles, so I probably did some mistakes. During my attempts to fix that bug, I discovered that there is a forgotten test file, fedoraproject.org/data/content/rss.html that pulls the redhat magazine feed, which takes long to download (longer than the fedora feeds). As we don't really use this feed, I suggest deleting this file for more speed improvements. [1] http://elad.fedorapeople.org/0001-Buildscript-can-now-work-parallel-impro...
