Use -mfloat-abi=softfp on armel for NEON instructions 

There was already a patch to do the same for Jewel, but it got removed
when the build system changed to cmake because it patched an autotools
file which was no longer present. This adds the same logic to the new
cmake based build system.

Closes: #913599
