Unfortunately, using something like (llvm10 is just one example,
llvm11 showed the same sort of problem at the time):

/usr/local/etc/poudriere.d/options/devel_llvm10/options:_FILE_COMPLETE_OPTIONS_LIST=BE_AMDGPU CLANG DOCS EXTRAS LIT LLD LLDB LLD_LINK OPENMP PYCLANG BE_FREEBSD BE_NATIVE BE_STANDARD
/usr/local/etc/poudriere.d/options/devel_llvm10/options:OPTIONS_FILE_SET+=BE_AMDGPU
/usr/local/etc/poudriere.d/options/devel_llvm10/options:OPTIONS_FILE_UNSET+=BE_FREEBSD
/usr/local/etc/poudriere.d/options/devel_llvm10/options:OPTIONS_FILE_SET+=BE_NATIVE
/usr/local/etc/poudriere.d/options/devel_llvm10/options:OPTIONS_FILE_UNSET+=BE_STANDARD

does not work for all platforms/targets. On a Cortex-A57
this lead to:

Registered Targets:
  amdgcn - AMD GCN GPUs
  r600   - AMD GPUs HD2XXX-HD6XXX

In other words, aarch64 was missing. I had to pick
BE_STANDARD or BE_FREEBSD to get something that
would target aarch64 on aarch64.
