Power architecture

Installing deal.II on Power architecture is pretty straightforward if you are using gcc. The only difficulty comes from TBB which is an Intel library. Therefore, the bundled version of TBB won't compile. Instead, you will need to download the patched version of TBB from here. You can download the code associated to any distribution since you are only interested in the source code. The easiest way to install TBB is to replace the include and src directories of the bundled TBB with the patched ones. Don't forget to replace the Makefile in src from the patched TBB with the CMakeLists.txt in src from the bundled TBB. Now, deal.II will install the patched TBB for you.
