volk: proposed solutions to bugs 582/583

582 and 583 are probably compiler bugs, and an upstream bug has been filed
on launchpad with Linaro GCC. A static cast of the tolerance is not happening
on armhf architectures. The work around forces a cast by using the values
immediately after assignment.
volk: fixup QA's fcompare to test all differences

This addresses bug 627 by adding a fabs call when checking if a number
is close to 0. If this is the case we also make sure the other buffer
is within tolerance. For the normal test case wrap the percent difference
in fabs rather than just the difference.
volk: add avx u/a protokernel for 32f_x3sum_of_poly_32f

The threshold differences have to change for volk_profile because
of rounding errors. It was passing previously because of a bug in
VOLK QA (bug 627) that has since been resolved.
volk/qa: For complex series, check the EVM rather than real/imag separately

volk: enabling unaligned protokernels for rotator

Added ifdefs so that the existing unaligned kernels get built and
tested.
