I understand that implementation_id is identified in 9ca2f16. If the 
configuration file does not contain implementation_id, it will be 
displayed as unsupported.

The error as follows:
config/arm/meson.build:227:2: ERROR: Problem encountered: Unsupported 
Arm implementer: 0x48. Please add support for it or use the generic 
(-Dmachine=generic) build.

Besides, we use the -Dmachine=generic, the bug is not resolved.
the cmd as:
  meson build or meson -Dmachine=generic build
