osmo-trx: different output in convolve test between x86 vs neon vs neon-vfpv4
I attach the output while running convolve_test (previously in utils/ directory) on a x86 with ssse3 and sse4.1. Now that I am implementing the infrastructure to run tests in ARM (see #2721), I found out that the output for this test is different in neon and neon-vfpv4 cases. The output is also different between the 2 neon ones. The arm testsuite.log files contains the diff aginst the x86 one (as it was the first one I used and the tool was initially wrote against it, it's the "expected" output").
I don't know if that's expected or if it's actually a bug. Assigning to Tom as he seems to be the one knowing more about this topic and who wrote the initial code for ARM.
