a3d7683c85 Fix segmentation fault of volk_gnsssdr_profile in 32-bit architectures 
Temporal deactivation of the unaligned protokernel of the multiple
correlator. It does not affect receiver's performance. The commit
includes other minor fixes.

db321d1c2e Fixing missing phase increment in SIMD implementations 
After computing the rotation with SIMD instructions, we were not
incrementing the phase step, so the first iteration in the 'c region'
had the same phase than the last sample computed with SIMD instructions.
This commit fix the bux in SSE3 and NEON implementations
