Review: Overall looks good and mostly ready to merge. some minor changes only:

• make main look similar to other posixutils, notably initializating the gettext system.
• remove final ".0" from object crate version. We prefer to auto-upgrade minor versions automatically. e.g. 0.35 not 0.35.0.
• include top-of-file copyright, which should be assigned to Hemi Labs, Inc.

And a more general review question: The object crate claims to support many formats. Is it possible to support files such as COFF without much additional code?

The code is based on the build API of the object crate, which is currently only available for the elf format (https://docs.rs/object/latest/object/build/index.html). There is a unified write API (https://docs.rs/object/latest/object/write/index.html), but it doesn't support writing executables. There are also format specific APIs (for example https://docs.rs/object/latest/object/write/elf/struct.Writer.html), but they are very low level and in my opinion would require a lot more code
