devel/llvm10 (and 11) on aarch64: only BE_AMDGPU registered targets despite OPTIONS_FILE_SET+=BE_NATIVE also being set

[Mark Millard]

Building devel/llvm10 via poudriere-devel on a Cortex-A57
system (OverDrive 1000), I ended up with just:

# /usr/local/llvm10/bin/llc -version
LLVM (http://llvm.org/):
  LLVM version 10.0.1
  Optimized build.
  Default target: aarch64-portbld-freebsd14.0
  Host CPU: (unknown)

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

from a context that has:

# grep -r BE /usr/local/etc/poudriere.d/options/devel_llvm10/
/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

(I've used the combination in various llvm*'s for years,
including using such for llvm10. Something has changed.)

I'll not repeat the material here but llvm11 got the same
sort of result.

May be that "Host CPU: (unknown)" has something to do with
it?

This has been true since I built and installed back on
2021-Feb-11 and is true of my updating build started
yesterday (bulk still in progress). LLVM10 pkg info

Description    :
The LLVM Project is a collection of modular and reusable compiler and
toolchain technologies.

This port includes Clang (a C/C++/Objective-C compiler), LLD (a linker),
LLDB (a debugger), an OpenMP runtime library, and the LLVM infrastructure
these are built on.

(So the above predates the git conversion.)

The issue was first noticed via build failures like (from a
log file):
