Summary	0000414: Missing handling for EM_AMDGPU and most other architectures
Description	file does not recognize the e_machine type for AMDGPU and many other registered EM_* values. It reports this as "unknown arch 0xe0
Steps To Reproduce	$ file amdgpu.o amdgpu.o: ELF 64-bit LSB shared object, unknown arch 0xe0 version 1, dynamically linked, not stripped Attached a random sample
Additional Information	Grepping the sources suggests the list of handled cases is much smaller than the list of registered elf machines: src/readelf.h:#define EM_SPARC 2 src/readelf.h:#define EM_386 3 src/readelf.h:#define EM_SPARC32PLUS 18 src/readelf.h:#define EM_SPARCV9 43 src/readelf.h:#define EM_IA_64 50 src/readelf.h:#define EM_AMD64 62 The current list of registered target IDs is at https://www.sco.com/developers/gabi/latest/ch4.eheader.html, all of these should be recognized
Tags	No tags attached.
