Using OPTIONS_FILE_SET+=BE_STANDARD instead of
OPTIONS_FILE_SET+=BE_NATIVE did not have this
problem. (I've not tried BE_FREEBSD so far.)
Also, my Cortex-A7 (so: armv7) context did not have
the "amdgcn/r600 only" problem with
OPTIONS_FILE_SET+=BE_NATIVE :
# /usr/local/llvm10/bin/llc -version
LLVM (http://llvm.org/):
LLVM version 10.0.1
Optimized build.

Registered Targets:
amdgcn - AMD GCN GPUs
arm - ARM
armeb - ARM (big endian)

So somehow specific to Cortex-A57/Cortex-A72 or to aarch64
generally. (The MACCHIATObin Double Shot had the same
build problem as the OverDrive 1000.)
It might be appropriate to disable the BE_NATIVE option
for aarch64 if it is going to silently not produce aarch64
support.
