--- Comment #36 from Jan Beich <jbeich@FreeBSD.org> ---
Mikael, have you tried to bootstrap Rust on armv7? For one, FreeBSD armv7
appears to assume NEON.

$ cc -v
FreeBSD clang version 5.0.0 (tags/RELEASE_500/final 312559) (based on LLVM
5.0.0svn)
Target: armv7-unknown-freebsd12.0-gnueabihf
Thread model: posix
InstalledDir: /nxb-bin/usr/bin

$ cc -dM -E -</dev/null 2>&1 | fgrep -i -e vfp -e neon
#define __ARM_NEON 1
#define __ARM_NEON_FP 0x4
#define __ARM_NEON__ 1
#define __ARM_PCS_VFP 1
#define __ARM_VFPV3__ 1
#define __VFP_FP__ 1
