We've been successful in building dependencies for gnuradio on armv7 platform, however while building GRAS, we got this error:

In my opinion this is an assembler issue for armV7, but I've got no leads on how to solve this. Will mapping this instruction with an equivalent assembly instruction for armV7 work?

Here's /proc/cpuinfo
