Merge branch 'next' of http://gnuradio.org/git/gnuradio into volk_rename
Cleans up the Makefiles for the various platforms. This should also make it easier to add new architectures. Thanks to Josh for the inspiration.
Volk: Build fixes to work with/without Orc.
Volk: More autotools stuff for Orc. Should build OK with or without Orc now.
Volk: Automated more automake for orc. Brought orcc generation in. Shared library libvolk_orc.la.Linking is hackery right now with specified -lorc-0.4 flags; this should change. Otherwise pretty much OK.
volk: committed some stuff i neglected
volk: Removing unnecessary shell script; last commit takes care if its functions.
volk: Working on VPATH build issues. Makes it through configure, fails on make.
Initial checkin for VOLK - Vector-Optimized Library of Kernels. This is a new SIMD library.
It currently stands by itself under the GNU Radio tree and can be used separately. We will integrate the build process into GNU Raio and start building off of its functionality over time.
