The recent 32-bit noise was related to a bad ifdef

The kernel in question volk_32f_binary_slicer_8 came in to
existence this past August or September, which is relatively new
in terms of volk kernels.
Here are my hunches on the culprit:
1) this is a case of an incomplete uninstall/reinstall of GNU
Radio where libvolk wasn't removed/replaced, but the gr binary
slicer block was.
2) there are multiple libvolks in different prefixes. An old
one is getting picked up at runtime
I'll be very surprised if there aren't multiple versions of
libvolk living in ld library paths

OK, cool.
It runs out that this is actually 64-bit hardware, so he's going to
go off and install a 64-bit OS instance on it, then try again. This
should be
a "virgin" system when he layers Gnu Radio on top of it.

This is a 32-bit install of Ubuntu 14.04, I don't know
exactly what type of hardware.
I vaguely recall noise about 32-bit VOLK installs becoming
confused, but I can't find that thread.
They installed using build-gnuradio, and that apparently
worked just fine (or, at least, didn't fail to the point
that build-gnuradio noticed).
