State-Changed-Why:
Is this still an issue?  I suspect the problem is that the netbsd-7
compiler was too old to recognize `.arch armv8-a' or `.fpu
crypto-neon-fp-armv8' together with `.arm' to make the rbit instruction
available in the assembler.  This logic is all gated on runtime CPU
feature detection anyway, so it shouldn't matter what ABI (earmv6hf)
your userland was built for.  I tested with a netbsd-10 compiler set to
`-march=armv6 -mfpu=neon' assembling an rbit instruction after the same
.arch/.fpu/.arm directives, and it worked fine.
