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).
