Merge branch 'next' into guile.

Passes distcheck.

* next: (32 commits)
  volk: Fix for popcnt's 64/32-bit issues.
  Using a copy of config.guess and config.sub instead of sym links.
  Including time header to qa files.
  Changed python env variable to more globally usable version.
  gr_uhd: Quick fix for make distcheck failures if UHD is not installed.
  PFB resampler: fix it this way to avoid the signed/unsigned warning.
  PFB resampler: fixes bug where filter could be looking past the number of inputs.
  resampler PFB: Sets relative rate when rate is changed.
  Create method to set rate on pfb_arb_resamp after it has been created. Allow it to be called from GRC.
  volk: fix for running 32-bit OS on 64-bit processor. System is correctly identified as 32-bit and compiles with the correct flags.
  volk: changing the path variables again. This works on my various systems tested. Using abs_ path names failed on Ubuntu 8.04 32-bit.
  volk: May be a hack, but it was required for my 32-bit Fedora 13 to work.
  volk: Removing unnecessary shell script; last commit takes care if its functions.
  volk: Fixing build system to handle making volk_mktables, volk_tables.h, and volk_config.h instead of a standalone shell script.
  volk: readding 16sc_magnitude_32f_sse with fix for SSE hadd_ps error.
  volk: Adding a few more generic-only test cases.
  volk: adding generic QA test for 16sc_magnitude_32f.
  volk: modified the configure scripts to output which architectures it will be building based on the configure tests.
  uhd: update notes in grc blocks for addressing scheme
  volk: Removing erroneous SSE function that actually usese an SSE3 intrin (mm_hadd_ps).
